Dear R-help, Please can someone explain how to put a column name on an output data.frame.
##Starting with a data.frame with 3 columns (d$Year, d$NoIndiv, d$wtd_tl) yr_ind <- split (d$NoIndiv, d$Year) yr_tl <- split (d$wtd_tl, d$Year) ann_ind <- sapply (yr_ind, sum) ann_tl <- sapply (yr_tl, sum) av_tl <- ann_tl/ann_ind d2<- data.frame (av_tl) ##This gives me a data.frame with columns, the second of which has a column name (av_tl) I have tried > d2<- data.frame (year = x, av_tl) > d2<- data.frame (x="year", av_tl) > d2<- data.frame (x="year", av_tl, check.names = TRUE) > d2<- data.frame (year, av_tl) as well as several combinations with cbind, as.matrix, etc... I cannot relate the examples given in ?data.frame with my problem or find a similar problem in the archives.
