Dear R-list,
I'm experiencing some problems while using "strptime", which I don't understand.
> str(natver)
'data.frame': 154 obs. of 8 variables:
$ ID : Factor w/ 14 levels "AC","ALS","FA",..: 10 11 9 1 4 8 13 3 14 12
...
$ CdBMin : int 22 22 26 26 28 23 27 23 25 26 ...
$ CdBMax : int 22 24 27 26 32 26 29 30 29 28 ...
$ Hrend : int 184 NA 120 168 NA 152 165 160 140 140 ...
$ Age : int 28 32 44 21 35 47 36 29 36 43 ...
$ Weight : int 63 70 80 57 69 74 82 71 85 70 ...
$ variable: Factor w/ 11 levels "X50","X100","X150",..: 1 1 1 1 1 1 1 1 1 1 ...

Do you what's wrong there ?
I'm working with R-2.5.0, under Windows 2000.
