Hi all, How can I convert factor like this:
str(repo)
'data.frame': 1000 obs. of 1 variable: $ AAA: Factor w/ 1000 levels "AAT","AAC",..: 1 2 3 4 5 6 7 8 9 10 ...
print(repo)
AAA 1 AAA 2 AAT 3 AAC ... into to simple vector
str(new_repo)
chr [1:100] "AAA" "AAT" "AAC" "AAG" "ATA" "ATT"...
print(new_repo)
[1] "AAA" "AAT" "AAC" "AAG" "ATA" "ATT"... I tried as.vector(), but it remains the same factor. - Gundala Viswanath Jakarta - Indonesia

Hi Bill, However with as.character it fail show the actual strings. It gives this:
new_repo <- as.character(repo) str(new_repo)
chr "1:32267"
print(new_repo)
[1] "1:32267" Instead of
str(new_repo)
chr [1:100] "AAA" "AAT" "AAC" "AAG" "ATA" "ATT"...
print(new_repo)
[1] "AAA" "AAT" "AAC" "AAG" "ATA" "ATT"...

But repo is a dataframe. AAA is a factor within repo. You probably need to apply as.character to repo$AAA.

Using 'str' to see what you have is excellent practice (and very helpful to show in messages to R-help). However, you need to look at the output you get more carefully. You have a data frame that contains a factor. So: as.character(repo[, 1]) should do what you want.
