adding lines to multiple plot
...I know in Matlab there is a hold function, is there something similar in R? the following is the code i have used to get mutiple plots and then add all the lines to the final plot: ##find unique column names in table variablenames<-unique(names(variables)) ## define number of unique names Nvariables<-length(variablenames) ##for loop required for labelling of histograms and to tell how many hist to make for(i in 1:Nvariables){ par(mfrow=c(1,1),ask=TRUE) } ##use lapply for dataframes creates hist for each variable and labels corresponding ##important to have this outside of loop lappl...

system is computationally singular: reciprocal condition number
...there is no way this is a singular matrix. I have uploaded the input file to my ftp: http://mkk.szie.hu/dep/talt/lv/CentInpDuplNoHeader.txt It is a tab delimited txt file with no headers. I tried the StatMatch Mahanalobis function and also this function: mahal_dist <-function (data, nclass, nvariable) { dist <- matrix(0, nclass, nclass) n=0 w <- cov(data) print(w) for(i in 1:nclass) { for(c in 1:nclass){ diffl <- vector(length = nvariable) for(l in 1:nvariable){ diffl[l]=abs(data[i,l]-da...

Pass Conditional & loop argument into a function
...# "X^1+X^2+X^3" fit <- lm(Y~conditional.argument) ... return(fit) } I know that there is the poly() function which I am not looking for. I am having this problem as well when I want to do a boxplot with variable number of groups to compare. multiple.boxplot <- function(...,nvariables){ conditional.argument <- data[,1], data[,2], ...,data[,nvariables] # should look like that in the end boxplot(conditional.argument) } Can anyone give me a hint?

random forest -optimising mtry
Dear R-helpers, I'm working on mass spectra in randomForest/R, and following the recommendations for the case of noisy variables, I don't want to use the default mtry (sqrt of nvariables), but I'm not sure up to which proportion mtry/nvariables it makes sense to increase mtry without "overtuning" RF. Let me tell my example: I have 106 spectra belonging to 4 classes, the number of variables is 172. I'm interested in finding information about variables (importa...
