Hello!
I posted this question earlier but it seems that something went wrong, so I
post it again.
I have a problem making a new variabel in a dataframe that consists of a time
difference. It seems that the new variable gets into the dataframe but I cant
look at it anymoore. Here is what happens. > tdiff<- difftime(Kontrolltid,
Starttid, units="auto")
> tdiff
Time differences in mins
[1] 168 NA NA 165 175 140 191 195 130 160 135 165 330 178 141 NA 119 90 70
[20] 99 115 70 65 90 90 65 90 75 85 93 52 75 60 90 105 70 65 60
[39] 85 110 65 60 98 62 71 61 41 80 67 83 72 73
attr(,"tzone")[1] "" > givnona<- data.frame(givnona, tdiff) names(givnona)
[1] "Vanna" "Datum" "Starttid" "Kontrolltid" "Zo.Höger"
[6] "Zo.Vänster" "Mm.Höger" "Mm.Vänster" "tot.zo" "tot.mm"
[11] "tdiff"
fix(givnona)
Error in edit.data.frame(get(subx, envir = parent), title = subx, ...) :
can only handle vector and factor elements tdiff <-structure(c(168, NA, NA,
165, 175, 140, 191, 195, 130, 160, 135,
165, 330, 178, 141, NA, 119, 90, 70, 99, 115, 70, 65, 90, 90, 65, 90, 75,
85, 93, 52, 75, 60, 90, 105, 70, 65, 60, 85, 110, 65, 60, 98, 62, 71, 61, 41,
80, 67, 83, 72, 73),
tzone = "", units = "mins", class = "difftime")> Any solution?cheers/Jojje
