Hi, I have the following input file. $ cat main.txt CEL_A CELL_B 1 4 2 5 2 6
Then I run read.table in R. > f=read.table('main.txt', header=T, check.names=F, sep='\t') > head(f) \ufeffCEL_A CELL_B 1 1 4 2 2 5 3 2 6 > f$CEL_A NULL I'm not sure where the special character \ufeff comes from. Could anybody let me know what is the problem?
