Hi all, It is recommended in ?'if' that we use 'else' right after '}' instead of starting a new line, but I noticed deparse() will separate '}' and 'else' when the 'if...else' clause is used inside {...} (e.g. function body). Here is an example: ## if/else inside {} > cat(deparse(parse(text='function(){if (TRUE) {1} else {2}}')),

Hi Everyone, I want to get the commands history as a character vector instead of just displaying them, but the function history() just returns NULL. I checked the source code of 'history' and could not find a solution. Anybody has an idea? Thanks! P. S. My original problem is, when a user opens a graphics device like png() or pdf(), I want to know the file name used by this device. I

Hello all, I'm having a problem when overwriting the '<-' function and was told I'd better post it here for help. The reason why I need to overwrite it is complicated and not easy to tell in a few words; but this seems the only clean option other than hacking R's core source code. My code looks like: # in .onLoad of a package; or if you want to test, put it in a function

Hi the list When two setGeneric occurs on the same function, the second erage the first and erase all the function previously define. Is it possible to prevent that ? Is it possible to declare a setGeneric that can not be erased later ? Something like the |sealed for setMethod...| || |Thanks| || Christophe

Dear all, My apologies for re-posting this question, but I have not found any solution to my problem so far. I also think that my post may have been overseen due to the posting time and high traffic on this list. I experience a problem in implementing a S4 class in a package and would appreciate your help in this matter. The class is implemented using Rcpp, which works well. I then extend

If you are wondering why RStudio did this, you can see their substitute function using (parent.env(environment(install.packages)))$hook They appear to do these things: - Allow package installation to be disabled. - Check if a package to be installed is already loaded, so that RStudio can restart R for the install. - Add Rtools to the PATH if necessary. - Trigger an event to say

I'm using the function htmlParse() in the XML package, and I need a little bit help on error handling while parsing an HTML page. So far I can use either the default way: # error = xmlErrorCumulator(), by default library(XML) doc = htmlParse("http://www.public.iastate.edu/~pdixon/stat500/") # the error message is: # htmlParseStartTag: invalid element name or the tryCatch()

This is an announcement of the release of an R package 'formatR', which can help us format our R code to make it more human-readable. If you have ugly (I mean unformatted) R code like this: ?# rotation of the word "Animation" # in a loop; change the angle and color # step by step for (i in 1:360) { ? # redraw the plot again and again
