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

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]-d...

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 (import...
