Subject: Splitting up of a dataframe according to the type of variables

Hi,
You could also use ?colwise() from library(plyr)
set.seed(50)
dat1<-data.frame(Col1=sample(1:20,10,replace=TRUE),Col2=sample(LETTERS[1:10],10,replace=TRUE),Col3=sample(LETTERS[11:20],10,replace=TRUE),Col4=sample(40:60,10,replace=TRUE))
?dat1[unlist(colwise(is.factor)(dat1))]
#?? Col2 Col3
#1???? D??? Q
#2???? C??? L
#3???? G??? R
#4???? A??? S
#5???? C??? N
#6???? G??? Q
#7???? I??? P
#8???? D??? M
#9???? A??? N
#10??? B??? N
?dat1[unlist(colwise(is.numeric)(dat1))]
A.K.

Subject: [R] Splitting up of a dataframe according to the type of variables
Dear R users,
I have a dataframe which consists of variables of type numeric and factor.
What is the easiest way to split up the dataframe to two dataframe which contain all variables of the type numeric resp. factors?
Thank you very much for your efforts in advance!
Best,
Martin
