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.
Ross
