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 ...
 $ value   : Factor w/ 47 levels "00:00:36","00:00:39",..: 1 2 4 3 3 4 5 7 8 6 ...

Erreur dans `$<-.data.frame`(`*tmp*`, "Time", value = list(sec = c(NA_real_,  : 
        le tableau de remplacement a 9 lignes, le tableau remplacé en a 154

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

Thanks for your help,
Best regards,
François
