Dear R helpers, I am new in R and I am having trouble with a function. I am proggraming a genetic analysis and there is a script that generates a lot of different matrix, for example x,y and z. And what I am trying to do is to loop the same script for different variables the user will define in the function. Therefore the matrix x, y and z are going to be created for each variable myfun <- function(...){ #the variables in (...) for example ("DAP", "Vol") Vec = matrix(c(...)) for (i in seq(along = Vec)){ ... ##generates x, y and z # The scripts are not here because they are big assign(paste("x",i,sep=""),x) assign(paste("y",i,sep=""),y) #this generates x1,y1,z1, x2, y2, and z2 for the example with two variables assign(paste("z",i,sep=""),z) } ####Here is the step of my doubt where I can?t solve #### I want to assign those variables in a list function structure(list(...), class = "genotype") ## In the example it would be ##structure(list(varX1 = x1, varX2 = x2, varY1 = y1, varY2 = y2, varZ1 = z1, varZ2 = z2), class = "genotype") } #end of function However I don?t know how to assign those variables in this list because I don?t know how many variables will the user declare I am not sure if I was clear, I know it is hard without the whole script, but I think it wouldn?t make any difference. It could be considered 3 randomly matrix generated each time (each loop). Thank you very much for the help and for the time dispended -- View this message in context: http://n4.nabble.com/Assign-variables-in-a-loop-to-a-list-tp956207p956207.html Sent from the R help mailing list archive at Nabble.com.
