Hi, I have a data.frame object: > a.df Methods Score 1 Northern 1.3544227 2 Northern 0.8302436 3 RT-PCR 1.0011360 4 RT-PCR 1.1149423
If I write it out with write.table, > write.table(a.df, file = 'data.txt', quote = FALSE, sep = '\t', row.names = FALSE) the data.txt is looks like: Methods Score Northern 1.35442268939541 Northern 0.830243615689926 RT-PCR 1.00113601434407 RT-PCR 1.11494230904995 My question is, can I merge the two "Northern" entries into one cell, like the "Merge Cells" in MS Excel ?
