@0nly4phil for the second example as.data.table() as well as a conversion to character seems to do the trick.
The transfer is done with “data.table”:
df1 <- knime.in
df1 <- as.data.frame(df1)
a <- as.character(df1$'Column Header')
a <- strsplit(a,split="")
b <-matrix(unlist(a),ncol=10,byrow=T)
df1$'splt'<-b
knime.out <- as.data.table(df1)
