Dear all, I am trying the barplot command but some of the labels are disappearing as there is not enough place on the graph to put them all. Here is an example of code that doesn't show all the labels: barplot(sort(runif(9,0,0.2),decreasing=TRUE),xlim=c(0,20),width=2,names.arg=c("first name","second name","third name","fourth name","fifth

Dear all, I would like to log the calls to my functions. I am trying to do this using the function match.call(): fTest<-function(x) { theCall<-match.call() print(theCall) return(x) } > fTest(2) fTest(x = 2) [1] 2 I can see "theCall" printed into the console, but I don't manage to convert it into a character to write it into a log file

Hi, I am manipulating xml objects using the package xml. With the version 2.10.1 this package included the function xmlToList that was converting the xml into a list straight away. This function seems to have gone when I moved to 2.13.0. Does someone has an equivalent for it? Thanks, Samuel [[alternative HTML version deleted]]

Hello, I was wondering if someone knows the formula used by the function lm to compute the t-values. I am trying to implement a linear regression myself. Assuming that I have K variables, and N observations, the formula I am using is: For the k-th variable, t-value= b_k/sigma_k With b_k is the coefficient for the k-th variable, and sigma_k =(t(x) x )^(-1) _kk is its standard deviation.
