Hello,
I'm trying to add a column to the following data frame. The new column
will contain "black" when the 5th column(if_TE_related) is
"TE_related", or "orange" when the 4th column is " " (space).
"chromo" "MSU_locus" "end5" "end3" "if_TE_related"
"chr04" "LOC_Os04g01006" 1032 2679 "TE_related"
"chr04" "LOC_Os04g01008" 7636 3951 "TE_related"
"chr04" "LOC_Os04g01010" 9521 10296 "TE_related"
"chr04" "LOC_Os04g01020" 17165 17437 " "
"chr04" "LOC_Os04g01030" 29372 18440 "TE_related"
"chr04" "LOC_Os04g01040" 30637 37300 "TE_related"
...
So, after a data manipulation, it should look like the following...
"chromo" "MSU_locus" "end5" "end3" "if_TE_related" "color"
"chr04" "LOC_Os04g01006" 1032 2679 "TE_related" "black"
"chr04" "LOC_Os04g01008" 7636 3951 "TE_related" "black"
"chr04" "LOC_Os04g01010" 9521 10296 "TE_related" "black"
"chr04" "LOC_Os04g01020" 17165 17437 " " "orange"
"chr04" "LOC_Os04g01030" 29372 18440 "TE_related" "black"
"chr04" "LOC_Os04g01040" 30637 37300 "TE_related" "black"
...
I have worked on the following code to do this job using function and
loop, but it is not working. If someone help me, I would really
appreciate!!!
The original data frame is Os.chr4.gene.new.
Gene <- Os.chr4.gene.new[, c("if_TE_related")]
Genecolor <- function(Gene) {
lg <-length(Gene)
for(i in 1:lg) {
if (Gene == "TE_related") {D1 <- (Gene == "black")}
if (Gene == " ") {D1 <- (Gene == "orange")}
}
Gene.color <- cbind(Gene, D1)
write.table(Gene.color, file="Gene_color1.txt", sep="\t", row.names=F)
}
Genecolor(Gene)
