I am trying to read in a R-formatted datafile using RPy. When I read in
the file using R and display the data, the column headers are included.
$ R
> attach(".RDatalongrun",pos=2)
> dat<-get("longrun",pos=2)
> dat[1:5,1:9]
time index lat lon agl grdht foot sampt temp0
[1,] -60 1 45.7993 -90.4651 220.1694 496.0374 0.1794837 51.8537 296.35
[2,] -60 2 45.7283 -90.7861 1187.4362 366.4808 0.0025203 0.7241 296.77
[3,] -60 3 45.7782 -90.5021 237.6977 496.0374 0.1530388 44.1661 296.39
[4,] -60 4 45.7706 -90.5811 976.4551 496.0374 0.1043193 30.1000 296.35
[5,] -60 5 45.8013 -90.4390 55.8362 496.0374 0.2078631 60.0000 296.30
However, I can't figure out how to determine the column headers when I
read in the same file with RPy.
