[datatable-help] subset between data.table list and single data.table object

[iembry]

Hi Matthew and Steve, thank you both for your suggestions.

I had not used the basename function before and that was what was keeping me
from moving forward along with my coding.

As Matthew has suggested I made a post at
http://stackoverflow.com/questions/18165373/interpolation-of-grouped-data-using-data-table
with the remaining question that I have.

This is my revised code:

big <- lapply(sitefiles,freadDataRatingDepotFiles)
big <- rbindlist(big)
setnames(big,c("y", "shift", "x", "stor", "site_no"))
big[, y:=as.numeric(y)]
big[, x:=as.numeric(x)]
big[, shift:=as.numeric(shift)]
big[, stor:=NULL]
big <- na.omit(big)
big[,y:=y+shift]
big[,shift:=NULL]
big[, site_no := sub(".exsa.rdb", "", basename(site_no), fixed=TRUE)]
setkey(big, site_no)
big <- big[aimjoin]

Once again, thank you both for your advice and suggestions.

Irucka
