Hello all, thanks in advance for the trouble. I can't reshape a particular large data.frame. I have used melt and reshape successfully before, alot.
I am trying to go from wide to long format. I wish to separate The named variables below into 3 groups : SYST, DIAST and PULSE, and have them vary according to their timepoint: BAS, PRE, POST, INI ..... 240. Currently: > dim(book) [1] 885 205 > typeof(book) [1] "list" > SYST<-grep("SYST", names(book)) > DIAST<-grep("DIAST", names(book)) > PULSE<-grep("PULSE", names(book))[1:11] > names(book)[c(SYST,DIAST,PULSE)] [1] "BASSYST" "PRESYST" "POSTSYST" "SYSTINI" [5] "SYST5" "SYST10" "SYST15" "SYST25" [9] "SYST40" "SYST60" "SYST240" "BASDIAST" [13] "PREDIAST" "POSTDIAST" "DIASTINI" "DIAST5" [17] "DIAST10" "DIAST15" "DIAST25" "DIAST40" [21] "DIAST60" "DIAST240" "BASPULSE" "PREPULSE" [25] "POSTPULSE" "INIPULSE" "PULSE5" "PULSE10" [29] "PULSE15" "PULSE25" "PULSE40" "PULSE60" [33] "PULSE240" > TIMES=c("BAS", "PRE", "INI", "POST", "5", "10", "15", "25", "40", "60", > "240") > recovery<-reshape(book, direction="long", > idvar=c(names(book)[c(SYST,DIAST,PULSE)]), > varying=c(names(book)[c(SYST,DIAST,PULSE)]), times=c("BAS", "PRE", "INI", > "POST", "5", "10", "15", "25", "40", "60", "240"), v.names=c("SYST", > "DIAST", "PULSE")) Error in `row.names<-.data.frame`(`*tmp*`, value = c("NA.BAS", "NA.BAS", : duplicate 'row.names' are not allowed In addition: Warning message: non-unique value when setting 'row.names': ‘NA.BAS’ I don't know what to make of this and would value anyone's help. Thank you.
