Hi Rolf,
I am a beginner for R.
I have a date frame raw. it contents the fields of pedigree.name, UPN,
Test.Result.tr_Test.Result1, Result.tr_gene1,
Test.Result.tr_Variant..nucleotide.1 ...... Test.Result.tr_Test.Result20,
Result.tr_gene20, Test.Result.tr_Variant..nucleotide.20
Basically, I want transpose the data frame from wide format into long format.
So, I hope the function can generate subset the those fields for 20 times,
rename them and then stack them into one long format data frame. After that, I
hope I can use "for" loop to do this.
And now, I don't know how to fix the error
Thank you,Kai

I would have thought the error message to be completely
self-explanatory. The object in question cannot be found. I.e. it
does not exist, in your workspace or in any of the data bases on your
search path.
It would appear that you have not created "Test.Result.tr_Test.Result1".
Why did you expect it to be present?
Moreover, the code of your function makes no sense at all, at least not
to *my* feeble brain. The quantities "raw", "Pedigree.name" and "UPN"
are not arguments of your function. How do you expect k_subset() to
know what they are?
cheers,
Rolf Turner
