Glad you figured it out, but just be aware that if you set one value
of the column to be a character, it will make the whole vector
characters. This could cause issues for analysis if you need numerics
or factors. If the column is supposed to be a factor to begin with,
set it to be so; if you hav
Hi all,
Thanks for the help. Jeffrey was right; my initial dataframe did not have
the columns defined for factors. I solved it using Jorge's example of using
as.character.
Sorry for not being more clear before.

Hi Wade,
Try (untested):
df2[j,1] <- as.character(f2$Site)[i]
If that does not work, which is very likely, could you please provide
commented, minimal, self-contained, reproducible code?
HTH,

Perhaps this will help:

Now:

[1] a a c
Levels: a b c

Because test3's first column,
Your example looks like you are assigning back to the first column of
df2 (Num). Is this what you are really doing in your code?
You need to follow the posting guide:

Could you give a small reproducible example please?
It is not clear to me what your looping structure is
doing, or what your goal here is.
There may be a much simpler method than introducing
subscripts.

Hi all,
I have a dataframe (df1) that I am trying to select values from to a second
dataframe that at the current time is only for the selected items from df1
(df2). The values that I am trying to save from df1 are factors with
alphanumeric names
df1 looks like this:
'data.frame': 3014 obs. o
7 matches
