What would you recommend for visualisation?

If you pre-order on amazon, you'll get the final version as soon as it's available.

No, I wish there was. Those were painstakingly drawn by hand.

No, because I don't use Jupyter notebooks.

I'm the author, and I'm happy to answer any questions. The book should be in print by (hopefully) the end of this year, or definitely by Jan 2017. The content will not change significantly, but there is will be minor fixes and a

I've tried this - it helps, but it's not a silver bullet. (And GitHub doesn't use it in PRs)

This is a real issue. I ask contributers to add a bullet at the top of NEWS.md and I frequently have to manually fix merge conflicts. This is only a problem if you're handling multiple PRs simultaneously so your project has to reach a

No, one language (Python) isn't the right tool for every job.

That's changed in the second edition of the book, based on the feedback I had from many people who were teaching ggplot2 to first time R users. If you've never used R before, neither base graphics nor ggplot2 is intuitive, so you&

Because the chances are you learning R to do data science/analysis. And you're best off spending a little extra work to learn the tidyverse - that investment pays off with an ecosystem of tools that all fit together to help you s

I disagree. The inconsistencies across the apply family makes them hard to learn, and the absence of an apply function for data frames is particularly frustrating. I obviously also disagree on what is idiomatic R. If you know ggplot2, there

No idea about Hadley?! Oh the horror :p

Btw it's called the tidyverse now ;)

I think this would really benefit from some thoughtful indenting to illustrate the structure. For example, instead of: SELECT members.firstname AS "First Name", members.lastname AS "Last Name" FROM borrowings

You can do it with httpuv, but it might a bit clunky. I think better websockets support, and better async generally, is on the roadmap for the next year.

JSON is often a pain because it's so hierarchical and un-dataframe like. I have a few notes on working with it here: http://r4ds.had.co.nz/hierarchy.html . `ifelse()` is a nightmare of a function but I don't think

To me, citing readr feels like citing the company that made your pipettes. It's just useful infrastructure.

Most R users aren't programmers, and a LISP-y interface, while powerful, tends to be intimidating.

by hadley 10y ago
It took me 5 minutes to figure out how that actually did work! That is rather esoteric code! (FWIW the reason that there's no native support in ggplot2 for this sort of smoothing is that I think it's a really bad idea as it tends

I totally buy that argument, but there's probably not a huge overlap in the set of "common tasks" for R and python.

That is not true. The FDA uses R internally, and there is no requirement that you must use any specific software tool. See https://www.r-project.org/doc/R-FDA.pdf for more details

I'd recommend reading http://r4ds.had.co.nz for an R workflow that eliminates a lot of those pain points. (Except for infix string concatenation - I've never really understood why people prefer that to paste(). Maybe

I would love to know what you mean by data wrangling because I think R has a lot of good tools for it.
116.
by hadley 10y ago
No. R is a language that is beautifully well suited to data analysis and interactive computing. Stat people don't use it simply because we don't know better.

Or plot(sin) plot(D(sin)) (Programming from memory on my phone so might be slightly off)

And on a log scale you probably want to set the minimum value to 1 since the log of zero is negative infinity (I suspect that's the root cause of your ggvis problem)

Very strongly disagree that understanding statistics is a prerequisite to learning R. There is a lot you can do with R with understanding statistics. I also dislike the claim that R is not a real programming language. It is. Just because it

I hope I didn't come across as "thou shalt not" - it's just never going to be high in my priority list. (And even for your use case I would think you'd be better off keeping the models in a list and saving that. The
