Hello all,
I have a set B and a dataframe df. I want to name the columns of the
dataframe after the elements of the set B.
For example, for set B with elements {{"P1"}, {"P2"}, {"P3", "P4"}} I want
to create a new dataframe with 3 columns named {"P1"} and {"P2"} and
{"P3","P4"}.
I tried colnames(df)<-(B). But it shows the elements as list, see below:
> colnames(df)
[1] "list(\"P1\")" "list(\"P2\")" "list(\"P3\", \"P4\")"
Second part of my question is what is the bests command to extract the
elements of a set?
Thanks,
Neha
