Hello,
Try the following example.
#install.packages("reshape2")
library(reshape2)
d <- data.frame(D=Sys.Date()+1:5, Temp1=1:5, Temp2=6:10, Temp3=11:15)
d
dm <- melt(d, id=("D"))
dm
If this seems familiar, then in your it should be id=c("Length", "Date")
if "Date" already is a data.frame column.
Hope this helps,
Rui Barradas

Thanks for reply Rui,
this is not exactly what i need. The way you proposed i get the data
structured like this :
Length, TempAtLocation1, TempAtLocation2....TempAtLocationN
What i'd like is to actuall get the data from each file in Columns, but they
should be binded in rows in one table...something like this :
Length, Date(or the name of each file), Temperature
.
.
file 1 .
.
.
.
.
file 2 .
.
.
.
.
file 3 .
.
.
.
.
file N .
.
.
In that way i would have only three columns, and each 970 inputs (rows) the
values woud represent temperature at different date (meaning imported column
from a new file).
Any ideas?
