So refusing to provide service is "intolerant"? Does this only works on "protected groups", or does it work in general? How about the baker is willing to provide service to the gay couple, but just not the gay wedding? N

I actually think you are more possibly to make mistakes in R than in Excel. Because in Excel you always see the results directly, and you can even easily catch an anomaly in a single cell. But in R it takes one more step to see the results

This number does not mean much. In the old days, more Chinese students rely on full scholarship to study in the US. Now, more and more rich Chinese kids (mostly come with very poor academic background) can study in the US. So the overall nu

"if 1 in a million are criminals"? NYC population is 8.6 million in 2017, so there are only 8~9 criminals in NYC? Wow. Come on, you should give a much better estimate.

"cherry picked"? There is no doubt that data.table is generally way faster than dplyr, unless you cherry pick a few use cases. The problem is that dplyr is much slower than data.table and RStudio is promoting tidyverse too much to

When I say another 911 I didn't mean another exact repetition, I meant another terrorist attack on large scale.

No. It's also not fair to raise taxes (on rich and middle class) to pay college for poor kids. It is fine to have certain amount of transfer from the rich and middle class to the poor to pay for basic things, but pay for college should
