Cannot get "==" operator to return TRUE

Petr,

Thank you! ?That is great.

Do you know of a way to print a string such that I can see whether it
contains a string or a no-break space?

Thanks,
Garrett

I have a data.frame named "df". The dput of df is at the bottom of this e-mail.
What I'd like to do is replace the "n/a " values with NA. ?On Mac OSX, it works
to do this:
df[df == "n/a"] <- NA

However, it does not work on Ubuntu. ?See below.

Thanks in advance,

x <- df[27, 4] # complete data.frame dput is below
dput(x)

"n/a?"

Hi.

This string contains a no-break space, not a space.

?"n/a?" == "n/a\uA0"

?[1] TRUE

?"n/a\uA0"

?[1] "n/a?"

Hope this helps.
