That's fine. Am I correct that this is the format you want for the output
file?
nams <- c("fldsampid", "CLP_ID", "sacode", "matrix", "etc.", "CL",
"PO4", "SO4AG", "AL", "AS", "B", "V", "Zn", "etc.", "ALK",
"ALKB", "ALKC", "SOLID", "DOC", "TOC", "NO3")
It seems a bit suspicious as you have etc. in there twice.
In any case if I understand what you want all you need to do is arrange those
names in the order you want and put them in a vector call it bb.
Then you simply say
newxx <- xx[,bb]
et voilàI
You may want to have a look at indexing in the Introduction to R to get a
feeling for what's happening herel
Below is a small example.
However I don't think your data.frame is quite what you think it is.
When I do str(xx) to look at the structure all your variables are being read in
as factors, which I suspect is not what you want. R tries to recognize what
type of variable is being read in and often seems to decide a character or even
a numeric variable is a factor
You may want to run the command
options(stringsAsFactors = FALSE)
before you load the data into the data.frame
I hope this is of some help.
