Dear all, for the first array I can get ten 2x2matrices (and I am partially happy for this). Now, I have problem with the 2nd array. It gives three 2x2 matrices for both rows, while it was "supposed" to give five 2x2 matrices in the first row and three 2x2 matrices ONLY in the second row. What cou

[R] why sd() can be applied to character vector?

Hi Jeff. I believe my Function #1 actually does use "%in%" to select the data. I use "%in%" all the time but, as far as I can tell, it can only return a vector of logical values. As a result, it does keep the order of the dataframe from which you are selecting data. It does not, however, appear

Re: [R] Getting error while running unix commands within R using system() function

To diagnose a problem in R it pays to pull apart your expression into a sequence of simpler ones. E.g., replace your expression system(" awk '{print "Hello"$1}' infile.txt") with the sequence sysCmd <- " awk '{print "Hello"$1}' infile.txt" system(sysCmd) and you will see an error when runnin
