User defined columns in phenodata

[oheil]

When user defines a new column in phenodata with spaces,"-" or similiar, e.g. "my-new-column", reading phenodata.tsv with

phenodata<-read.table("phenodata.tsv", header=T, sep="\t")

results in column name of dataframe phenodata as"my.new.column".

Subsequent matches to a column parameter will fail.
