Undefined Columns Selected Error if Strange Variable Names Present

[DarioS]

If some strange omics identifiers are some of the column names, the imputation fails.

> colnames(iris)[2] <- "IGHV3-43D;IGHV3-9"
> missRanger(iris)
Missing value imputation by random forests
Error in `[.data.frame`(data, , relevantVars[[1L]], drop = FALSE) : 
  undefined columns selected

Can you make it more bioinformatics-friendly?

Thanks for reporting. This is a known but unfortunate issue.

I once attempted to fix it (#19), but could not find a good solution.

A fix would additionally require to replace ranger's formula interface by the "x/y" interface, which might solve another problem (#50).

I will keep the issue open. As it is complex, you can't expect a solution soon.

Fixed in #52
