[R] RE: Matrix to data.frame without factors

[Mäkinen Jussi]

Sorry, last answer slipped away because accidental key shortcut typing.

Thank you for your reply. Here is a sample of my data.frame (KUNTADATA):

KUNTADATA[1:10,c(6:8, 20)]
                            Kunta Period Name Asunnot 1100 intarr_14
1  ESPOON KAUPUNKI                     1993/1        14164  41336.27
2  ESPOON KAUPUNKI                     1993/2        14164        NA
3  ESPOON KAUPUNKI                     1994/1        14164      0.00
4  ESPOON KAUPUNKI                     1994/2        14164    330.29
5  ESPOON KAUPUNKI                     1995/1        14164      0.00
6  ESPOON KAUPUNKI                     1995/2        14164      0.00
7  ESPOON KAUPUNKI                     1996/1        14164  67277.18
8  ESPOON KAUPUNKI                     1996/2        14164   7860.26
9  ESPOON KAUPUNKI                     1997/1        14164        NA
10 ESPOON KAUPUNKI                     1997/2        14164 231701.05


So there is both character vector and numerical vectors. But truly - I could
just use na.to.0 when neccessary with numerical rows. But because I have
face this "problem" with factors quite often I though that it might be a
common interest to ask my question.

Still I cannot understand the result:

> is.numeric(as.matrix(KUNTADATA[,15]))
[1] TRUE
> is.numeric(as.data.frame(as.matrix(KUNTADATA[,15])))
[1] FALSE


Yes, your code works nicely (as always) and do the trick I wanted, something
I couldn't write down myself. There is for me a lot to learn within R/Splus.
Thank you, I appreciated your help and this list,
