...w to R and would like to know how to create a vector of "rolling sums". (I have seen the Rmetrics package and the rollMean function and I would like to do the same thing except Sum instead of Mean.) I imagine someone has done this, I just can't find it anywhere. Example: x <- somevector #where x is 'n' entries long #what I would like to do is: x1 <- x[1:20] output1 <- sum(x1) x2 <- x[2:21] output2 <- sum(x2) x3 <- ... ouput <- c(output1, output2, ...)

Hi, Is there any documentation to explain R's error diagnostics, e.g. messages like >source("../src/sources/routine.R") Read 8 records Read 2 records Error in "[<-"(*tmp*, !test, value = rep(no, length = length(ans))[!test]) : incompatible types The nature of the problem incompatible types, is clear; but I'm more interested in its location, and feel

Hello, Is the first time I am using SNOW package and I am trying to tune the cost parameter for a linear SVM, where the cost (variable cost1) takes 10 values between 0.5 and 30. I have a large dataset and a pc which is not very powerful, so I need to tune the parameters using both CPUs of the pc. Somehow I cannot manage to do it. It seems that both CPUs are fitting the model for the same values
