Functions and tips for use in the R statistical environment. Friday, August 28, 2009. I have been trying to convince my collaborators to use git so that we all work on the same page; however, I have accepted the fact that not everyone wants to get that involved. For these collaborations, I have started relying on a free web-based service called Dropbox. On Linux, after downloading and installing the program, you just have to start the daemon:.

Functions and tips for use in the R statistical environment. Monday, July 20, 2009. When subversion does not add up. I have been using Subversion to manage all of my active projects - it is a fantastic tool but I ran into a bit of a problem recently when I accidentally added several hundred log files as I was preparing for a commit (using the automated method I describe here. Most suggestions I found on the internet were some variation of:. Svn - recursive revert . Svn st grep log badfile.txt.

Functions and tips for use in the R statistical environment. Friday, May 16, 2014. Sample uniformly within a fixed radius. I was asked how to do this today and thought that I would share the answer:. Sample points uniformly within a fixed radius. NB: To get a truly uniform sample over the circle, you must. Sample the square of the distance and then transform back.

Functions and tips for use in the R statistical environment. Wednesday, November 10, 2010. At last. I have been suffering with XEmacs displaying odd characters instead of the quotation marks that are used in R help files. This was driving me up the wall because it makes the files (and R output in general) very hard to read; however, I finally diagnosed the problem: Xemacs was not recognizing UTF-8 encoding. Below is a quote from Marjan Parsa. How can I get XEmacs to work with UTF-8 files? Caution: I have...

Functions and tips for use in the R statistical environment. Saturday, December 13, 2008. R matrices in C functions. Using the .C() function in R, you can only pass vectors. Since R stores matrices columnwise as vectors anyhow, they can be passed to your C function as vectors (along with the number of rows in the matrix) and then accessed in familiar [row,col] manner using the following C functions (idea from here. Vector loc, int. Converts vector notation into row-col notation*/. View my complete profile.
