[R] use tapply in a list which contains many data.frame

I have a list like the following: class(temp) [1] list names(temp) [1] 1A24 1A57 1A5J 1A6X 1AB7 1AF8 1AFI 1AGG 1AH9 1AHL [11] 1AJ3 1AJW 1AK7 1ALG 1AOY 1APF 1AUZ 1AZJ 1AZK head(temp[[1]]) pr modelaa omega 1 1A24 MODEL_1 1_ALA 84.47 2 1A24 MODEL_1 2_GLN 63.06 3 1A24 MODEL_1

[R] use tapply in a list which contains many data.frame

In order to make this question be clear, Here is my code source(http://omega.psi.iastate.edu/data/nmr_19.R;) class(temp) [1] list names(temp) [1] 1A24 1A57 1A5J 1A6X 1AB7 1AF8 1AFI 1AGG 1AH9 1AHL [11] 1AJ3 1AJW 1AK7 1ALG 1AOY 1APF 1AUZ 1AZJ 1AZK head(temp[[1]]) pr modelaa

This should work on your data using the 'reshape' package; nmr_19_model_aa-read.table(url( http://omega.psi.iastate.edu/data/nmr_19_model_aa.txt;),sephttp://omega.psi.iastate.edu/data/nmr_19_model_aa.txt%22),sep =) name.col-c(pr,mod,mod_No,aa,aa_po,omega) colnames(nmr_19_model_aa)-name.col
