Hie Alaiso,
try to simply apply lapply() to your data frame. It should work w/o any
further operation since data frames are lists (check with is.list()).

Hi all,I would like to use an expand.grid functionality that would give
me at the end a listso far my code looks like:
sigma_max_On_seq<-seq(0.05,100,length.out=10000)
mean_max_On_seq<-seq(2,10000),length.out=10000)
expandMeanSigmaOn<-expand.grid(mean_max_On_seq,mean_max_On_seq,sigma_max_On_seq,sigma_max_On_seq)
that gives me at the end all the possible combinations as a data
frame.
Browse[1]> str((expandMeanSigmaOn))

but I want to have a list that I would be able to use it as input into
a lapply function. The lapply should use then each list entry
independently giving as input variables only the current
$Var1,$Var2,$Var3,$Var4
How I can convert in R the data.frame into a list?
I would like to thank you in advance for your replyRegardsAlex
