Hi,
I want to split a dataframe based on a grouping variable (in one
column). The resulting new
dataframes should be stored in a new variable. I tried to split the
dataframe using split() and
to store it using a FOR loop, but thats not working so far:
df <- data.frame(A=c("A1","A1","A2","A2"),B=seq(1:4))
Fsplit <- function(x,y){
ls <- split(x,f=x$y)
for (i in names(ls)){
i <- ls$i
}
}
Fsplit(df,A) #1st argument is dataframe to split, 2nd argument
grouping variable
It appears you want the name of the levels of df$A to be the names of
separate variables in the global environment. If that is correct, then
see the FAQ. I'm not sure which one it is among the Miscellaneous
section, but you should be looking of the one that tells you how to
construct a named variable.
Or:
