Dear R People:
I'm trying to replicate something that I saw on an R blog.
The first step is to load in the .rda file, which is fine.
However, some of the names of the columns in the data frame have
special characters, accents, and such.
Most of the world think characters with accents are normal, not special.
The difference for R is going to be whether they are alphanumeric or not.
How do I get around this on a basic keyboard, please?
Copy-and-paste from names(dataframe) may work. But without an example
or knowing your OS or your locale (but I remember you are in the US) it
is hard to tell.
The main issue is that what R regards as a valid name aka symbol depends
on the locale, and so strictly in a US locale no non-ASCII characters
are valid in names. In practice US locales tend to be set up either for
a Western European character set (Latin-1, cp1252) or so that all
alphanumeric Unicode characters in a human language are regarded as
alphanumeric.
Thanks,
Erin
