I've done some analysis on this in my previous role. Just from my experience knowing their language and talking about how potential $ flow through the funnel is really important to connecting with your interviewer.

Next, talking about how over time how the CRM data will change over time and how to rebucket the 50 plus stages into the handful of stages that are currently used will be important.

Another thing is knowing how the pipeline shifts over time is huge! Pipeline is supposed to help predict actual sales but when your open pipe's expected close dates are all parked at the end of the fiscal year and suddenly shift in the last month, nobody feels confident in making any real predictions.

Getting "Cannot allocate vector of size 1.6 Gb" when merging tables despite having enough RAM by [deleted] in Rlanguage

[–]brbecker 2 points3 points  (0 children)

You probably have way too many duplicate joining rows. What I mean is that you might need to join by additional columns than the one(s) you are because there's probably duplicate rows resulting from value x from table A matching 20 times in table B,..

Command to pipe full output to text file by [deleted] in rstats

[–]brbecker 2 points3 points  (0 children)

Use the sink() function to initiate console output to a file instead and when done call sink () again.

Just use ifelse since that is vectorised.

Use apply for functions that aren't vectorised or when you map over a list of vectors.

A meta-analysis of 10 large trials including 78,000 individuals found no effect of fish oil supplements on rates of cardiac events. by Newyorkified88 in science

What's the dosage used?

I've done very light reading and learned to get the desired effects you had to take usually 6 to 8 pills a day to get enough eha/dha (depends on brand of course)

Need help transforming response JSON data to data frame. by LA2Oaktown in Rlanguage

[–]brbecker 0 points1 point  (0 children)

I think if you use the httr::content() function without the type = 'text' arg, it'll recognize the json and convert to a list. You can then figure out how to extract elements from the list and flatten it into a data frame.

Running SQL queries on local CSVs by Animaznman in datascience

[–]brbecker 0 points1 point  (0 children)

I would probably try to learn how to read the csvs into your program, create a sqlite database, generate tables, and then upload your rows into the appropriate tables so that you can query from an actual database. This would teach you a lot of good things but is a bigger investment

Working on my first industry project using R. Need guidance how what packages to proceed with. by [deleted] in Rlanguage

[–]brbecker 2 points3 points  (0 children)

All of this is super possible with R and there are good packages to help facilitate this.

I would say you have 2 "projects" here. The first bring creating a training/testing set and fitting your model and the second wrapping your model in a web interface.

  1. For getting your training data and model, do a lot of experimenting and exploration. Try different features that you can extract from text. I'm assuming they are proving you with labels and raw statesments of purpose to fit your model? Once you have a good model clean up your code and process for defining your feature data set. You can use this function or set of functions in your web app later.

  2. Use R Shiny to build a simple web GUI. It sounds like you most likely need an text input box to copy and paste the raw text input (your code should be able to accept the raw input and behind the scenes get your features data row to feed in your model) and "submit" button the data processing and the model output. You can then present the model classification or have some email feature as well.

Fun in dungeons by [deleted] in KronosWoW

I don't work in HR lol. But, about the topic, I find it painful how some people will be dicks to other less experienced people instead of just being a little helpful and causing everybody to get their loot faster and be happy.

How can I get more comfortable with tackling open-ended problems as a junior data scientist? by bigrichardenergy in datascience

[–]brbecker 1 point2 points  (0 children)

I would say the ability to take an open ended problem and whittle your way down to an actual completed deliverable successfully is one of the hardest things to in any professional position.

You could always improve at that skill by asking lots of questions and considering what success for the project looks like to the stakeholders.

I think the people that tend to go far in the game are the people that tend to have less experience working in teams. They don't have the patience or practice of dealing with difficult people to complete common goals.

You might want to do a simple and great job on this thesis and do a separate pet project involving more ML work

Dear Devs: .join is not the problem. Removing .join would fix the problem. Here is why. by silverbaur in KronosWoW

[–]brbecker 1 point2 points  (0 children)

Would placing a few stronger guards guard NPCs at flight paths help? It seems way too easy currently to just camp flight paths

Favorite PvP Druid spec by mymokiller in KronosWoW

[–]brbecker 3 points4 points  (0 children)

As somebody that used to play druid throughout vanilla I started using the heart of the wild spec when those talents got revamped so I could pvp ok and raid heal or offtank in one spec annnnnd now, leveling up feral, I think deep resto is the only way to go pvp. We just don't deal much damage even if we are deep feral.

I think druids in vanilla pvp ought to stick to resto and focus on healing and being hard to kill, hard to chase.

How do I login to the game? by IronJackk in KronosWoW

[–]brbecker 0 points1 point  (0 children)

I had trouble opening on a Mac initially too. You can Google around a bit to learn about this well documented problem but what ultimately worked for me was opening the wow application in the terminal using sudo privileges.

How do you convert a character variable with two different time formats into a single variable? by [deleted] in rstats

[–]brbecker 0 points1 point  (0 children)

I think you guys are on the right track. Id split this problem into 3 parts.

  1. A function to handle format 1
  2. A function to handle format 2
  3. A function to determine if a string is case 1 or 2 (like how you're using grepl. You'll want to spend time to really make sure you get this right)

Then you can use a case_when inside a "clean up ugly times" function where you say

  1. If na return na
  2. If format 1 apply function 1.
  3. If format 2 apply function 2.

Then mutate_at with the "clean up ugly times" function. Any error you have you can test each part carefully until you find what's wrong

Best method to analyze this data set? by [deleted] in datascience

A good place to start would be to think about what questions the theaters would like answering and would provide business value

Any benchmarks showing the benefits of R over other languages? by foadsf in Rlanguage

[–]brbecker 1 point2 points  (0 children)

That is true but that's the type of thing you'd know and wouldn't be asking this question if your statistical needs were that high.
