I use a lot of R. The thing that drives me insane is when you create a function such as multxy <- function (x){x * y}, then you call multxy(6) R will not return an error as long as y is in the parent environment. That's pretty insan

R had changed a ton in the last three years. It's pretty clean these days.

That happens anyway. The Hillary Foundation and the American Red Cross have come under fire for doing just that.

I've taken a lot of statistics classes. Not once were random forests mentioned. Boosting was. Gradient boosting wasn't. Linear and logistic models were mentioned, but those are day 1 data science.

But they can be ordered and are represented as integers. So you can turn your numerics to factors and keep them in order and do whatever goofy math you want to do on your categorical data.

R data frames have excellent support for missing and categorical data. Everything else is just as much of a problem.

This particular pipe comes from F#. Let's say I have a table called dat. dat %>% filter(col_a == 'Good') %>% group_by(col_b) %>% summarize(n = n(), sum_c = sum(col_c)) To do this in traditi

What's wrong with R? I know it's not a programmers language but it's great for getting things done.

Sample size is too small and correlation does not equal causation are the worst. Teachers did a great job teaching those things, but sometimes correlation does equal causation or at the very least is interesting enough to warrant a closer l

I didn't try any. I drink very little wine. I did show the list around and no one was surprised. It wasn't Kendall-Jackson that was under priced. It was smaller wineries that had been getting solid reviews. There must have been so

In 2013, I got taste and aroma for around 1100 wines. I used the data to create flavor profiles and predict the price based on the chemical composition. In general, more expensive wines are more complex and the predicted price matches the a

If an introvert is quiet and no one is there to hear it, is he still an introvert?

It's the immediate feedback. The problem comes when the programs grow and the feedback is no longer immediate.

Not many. The punishment for voting when you are not a citizen is banishment. Which means that they are risking a lot for essentially nothing. Americans won't vote and they have every reason to do so. Why would illegal immigrants vote

No. Because there is no clear and immediate danger.

If you are fluent in R, why are you looping over a data frame?

Between dplyr, ifelse, and apply family functions, I don't think I've ever had to iterate over a data frame in R.

That's a 'soft brick'. It's a strange term, but necessary to differentiate from phones that will never turn on again. It's difficult to brick a phone these days.

More than that, I don't want to read all the comments. I just want to read the good ones. Without knowing which comments are good, I read the first set and move on to the next story.

I know that feeling. I was cruising along in my brand new BMW. Missed a couple of payments and I had to go back to my Honda Civic. It must be just like that. Most people that I know use a mouse, which has better scrolling and is much more p

I don't understand why people need such high resolution. Most people don't have the eye sight to see the difference.

Only two of those points are defensible. My computer still looks like it did back in 1995. The monitor is thinner. The mouse is a little more ergonomic. The keyboard looks the same. Tablets look like they did when Moses was holding up the T
