Hello!
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 hapens.
> tdiff<- difftime(Kontrolltid, Starttid, units="auto")> tdiffTime 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
> 73attr(,"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
