How to save list where each element contains equal number of values to a text file in R?
If we want to save a list to a text file then first step would be converting that list to a data frame then write.table function can be used for saving. For example, if we have a list defined as LIST and it has elements each containing 50 values then we can convert it to a data frame as −
LIST_df=as.data.frame(do.call(cbind,LIST))
Now we can save it as −
write.table(LIST_df,"LIST.txt")
Example
Consider the below list −
x1<-rnorm(20) x2<-rpois(20,10) x3<-rexp(20,1.25) List<-list(x1,x2,x3) List

Creating a data frame of List −
Example
List.df=as.data.frame(do.call(cbind,List)) List.df
