Dear all,
I have a data frame in which the columns need to be ordered. The first column X
is at the right position, but the remaining columns X1-Xn should be ordered
like this: X1, X2, X3 etc instead of like below.
> colnames(pos1)
[1] "X" "X1" "X10" "X11" "X12" "X13" "X14" "X15" "X16" "X17" "X18" "X19"
"X2" "X20" "X3" "X4" "X5" "X6" "X7" "X8" "X9"
> pos1[1:5,1:5]
X X1 X10 X11 X12
1 100.5 7949.469 18509.064 8484.969 17401.056
2 101.5 3080.058 7794.691 3211.323 8211.058
3 102.5 1854.347 4347.571 1783.846 4827.338
4 103.5 2064.441 8421.746 2012.536 8363.785
5 104.5 9650.402 26637.926 10730.647 27053.421
I am trying to first change the first column name to something without an X and
save as a vector. I would then remove the X from each position use the vector
for renaming the columns. Then the column 2-n could be ordered, I hope...
colnames(pos)[1] <- "Mass"
columnNames <- colnames(pos)
Does any of you have an idea how to do this, or perhaps there is a smoother
solution?
Would it be easier to solve it if the contents of the first column were
extracted and used as row names instead?
Best regards,
Joel
