Feed list of vectors to vioplot()?
<posted & mailed>
Thanks for the very appropriate scolding.
Here's my example (based on "?vioplot"):
mu<-2
si<-0.6
bimodal<-c(rnorm(1000,-mu,si),rnorm(1000,mu,si))
uniform<-runif(2000,-4,4)
normal<-rnorm(2000,0,3)
# Working just fine
myfunction1 <- function(x, ...){vioplot(x,...)}
myfunction1(bimodal,uniform,normal)
# What I (believe to) need
myfunction2 <- function(x, ...){
mylist <- list(x, ...)
# plenty of "lapply" stuff
vioplot(mylist)
}
myfunction2(bimodal,uniform,normal)
--> Error in min(data) : invalid 'type' (list) of argument
I'm at a loss on how to disentangle "mylist" - unlist just gives me one big
vector back rather than the 3 I want to have back ...
Thanks for your patience, Joh

It is hard to provide a solution if we do not understand the problem to be solved. Sample data would be helpful along with an understanding of what you would expect for output.

I'll try less impolite and with more info ... I'm writing a function that contains this: # function(x, ... , morestuff){} which is gathered into a list like so: # mylist <- list(x, ...) down the line I'd like to output all elements from "mylist" in seperate vioplots in a single coordiante system. Now I have a hell of a time with that because vioplot does not accept a list as input but only a succession of vectors ... how can I now force my list into that form so a can say # vioplot(magicfunction(mylist)) and get a violin plot for each list-member?
