Dear all,
I am trying to avoid a for loop here and wonder if the following is possible:
I have a data.frame with 6 columns and i want to get a cross-correlogram (by using ccf) . Obivously ccf only accepts two columns at once and then returms a list.
In fact, with a for loop i´d do the following
for (i in 1:6) {
x[[i]]=ccf(mydf[,i],mydf[,6])
}
Is there any chance to the same with lapply? e.g. lapply(mydf,"ccf", .... ) with ... respresenting the changing arguments for ccf functions (note only the first argument does actually change)
thx for any suggestions in advance
best
matt
