Hi,
I have a column which I have to convert from factors to numeric. I am using
the command as.numeric(variable) to do this. But when I convert the numeric
value becomes different from factor . for example.
> class(B)
[1] "factor"
> B
[1] 180 <NA> 183 175 163 155 <NA> 188 191 160 170 165 152 170
165
[16] 163 160 163 165 <NA>
> as.numeric(B)
[1] 46 NA 47 42 30 26 NA 49 50 29 37 32 24 37 32 30 29 30 32 NA
Is there a different way to convert factor to respective number ?
also when i try to unclass it i get following output
> unclass(B)
[1] 46 NA 47 42 30 26 NA 49 50 29 37 32 24 37 32 30 29 30 32 NA
attr(,"levels")
[1] "102" "104" "107" "109" "110" "112" "114" "117" "119" "122" "124" "125"
[13] "127" "129" "130" "132" "135" "137" "140" "142" "145" "147" "150" "152"
[25] "153" "155" "157" "159" "160" "163" "164" "165" "166" "167" "168" "169"
[37] "170" "171" "172" "173" "174" "175" "177" "178" "179" "180" "183" "185"
[49] "188" "191" "193" "196" "198" "201" "203" "211" "46" "48" "51" "56"
[61] "58" "60" "61" "63" "64" "65" "66" "69" "71" "74" "76" "79"
[73] "81" "84" "86" "89" "91" "94" "97" "99" "U"
Any help will be appreciated.
Thanks a lot.
