Use only ASCII characters in R code

[nfrerebeau]

Portable packages must use only ASCII characters in their R code.

@nfrerebeau Not really, but you have to define UTF-8 in the DESCRIPTION file.

[nfrerebeau]

Encoding is already defined in DESCRIPTION:

Al2O3_AnalysisApp/DESCRIPTION

Line 34 in 14165c7

Encoding: UTF-8

Am I missing somthing?

Got it; I saw the error now. It comes from the column names with µm etc. OK, I have no immediate solution.

@nfrerebeau I browsed a little bit through the problem. The Unicode characters are used mainly for the units in the tables. R supports a portable way for Unicode characters, but only in character strings. It does not work for column names because all characters are prompted as is. I see one solution by using tibbles instead of base R data frames. They can handle the encoding properly. For instance, df is a tibble it would read:

colnames(df) <- "\u00B5"
df[1,]

# A tibble: 10 × 1
       µ
   <int>
 1     1
