remove a row from a dataframe, row names disappear
I find this odd because it doesn't appear to happen in larger datasets. I
have the following data set ENV with the first column set as row.names:
> ENV
TPlog
001S29H 0.601
002S42H 0.602
003S43S 0.779
004S43S 0.702
005S51H 0.978
006S52P 2.718
If I apply > ENV <- ENV[-1,] # remove first row of data (right?)
...ENV comes back as:
[1] 0.602 0.779 0.702 0.978 2.718
So I am losing the row name info. I also notice that, if the first two
values...
