[R] Vary an equation using values from a sequence

Hi All, I have a vector of data on which I am operating. The equation with which I want to operate on the vector has a value k. I want to run the equation and output a new vector, each time replacing k with each value from the sequence I defined. I have thought about using for loops and such,

Re: [R] Fwd: Learning advanced R

I've found the solution to compile the adv-r-book from source: After doing some settings (see: https://travis-ci.org/hadley/adv-r/jobs/353347080/config ) and installation of netlify-cli, the command-line is: Rscript -e 'bookdown::render_book("index.Rmd","bookdown::pdf_book")' This works fine.

I've found two problems in interpreting adv-r-master/book/build-book.r: 1. All pathes in build-book.r refer to the starting-directory "adv-r-master". However, the script build-book.r is located in the directory "book", which is located in directory "adv-r-master". Therefore, pathes starting at

Hi Akshay, (Please include r-help when replying) You have learned that PFC.NS and snl[[159]] are not identical. Now you have to figure out why they differ. This could also point to a bug or a logic error in your program. Figuring out how two objects differ can be a bit tricky, but with

I don't think that warning is originating from R... LC_TYPE is an environment variable that the standard C library pays attention to, so could be either ssh on your local computer or ssh on the remote computer in response to something the local ssh is doing. IMO this question belongs in a

Hi Akshay, Presumably PFC.NS and snl[[159]] are not exactly the same. You can start by trying to determine if (and then how) they differ. e.g. > identical(PFC.NS, snl[[159]]) presumably this will result in FALSE then compare > class(PFC.NS) > class(snl[[159]]) etc HTH, Eric On Wed, Mar 14,
