Re: [R] Output for pasting multiple vectors

This has nothing to do with your problem, but given the heavy use of "=" to bind keyword parameters in R, I find the use of "=" for assignment as well confusing. It makes code harder to read than it needs to be. The historic " <- " assignment makes the distinction obvious. On Wed, 26 Jun 2019 at

Re: [R] Output for pasting multiple vectors

Hello, The following works. First, get the colnames you have posted in a format that R can process. in your code you would skip this. cnames <- scan(what = character(), text = ' "sample.NA.NA.NANA" "TCGA.27.1832.01.NA.NA.NANA" "TCGA.27.1831.01.NA.NA.NANA" "TCGA.28.5216.01.NA.NA.NANA" "TCGA.16.

Doing so results in the following subset of my data... >colnames(meth)[1:10] [1] "sample.NA.NA.NANA" "TCGA.27.1832.01.NA.NA.NANA" "TCGA.27.1831.01.NA.NA.NANA" [4] "TCGA.28.5216.01.NA.NA.NANA" "TCGA.16.0846.01.NA.NA.NANA" "TCGA.28.5218.01.NA.NA.NANA" [7] "TCGA.06.0178.01.NA.NA.NANA" "TC

Re: [R] Output for pasting multiple vectors

So I can run the suggested `stringsAsFactors=FALSE` argument following the 'colnames(meth)[1:10]' one I just used? Best, Spencer On Tue, Jun 25, 2019 at 3:28 PM Jeff Newmiller wrote: > A "very large" output from dput(head(meth)) may just mean that"meth" has > factors instead of character colum

Re: [R] Output for pasting multiple vectors

A "very large" output from dput(head(meth)) may just mean that"meth" has factors instead of character columns. I recommend using the `stringsAsFactors=FALSE` argument if the data frame is being loaded using read.table or one of its variants. It almost always makes better sense to create factors

Mr. Barradas, Oh haha my mistake. The following is the output you requested [1] "sample.NA.NA.NANA" [2] "TCGA.27.1832.01.NA.NA.NANA" [3] "TCGA.27.1831.01.NA.NA.NANA" [4] "TCGA.28.5216.01.NA.NA.NANA" [5] "TCGA.16.0846.01.NA.NA.NANA" [6] "TCGA.28.5218.01.NA.NA.NANA" [7] "TCGA.06.0178.01.N

Hello, No I wasn't expecting a very large file. Try to make a reproducible example. If the problem seems to be with the sapply/strsplit post a subset of the data like just some of the colnames: colnames(meth)[1:10] This would allow us to run the code you are having trouble with. Hope this

The result of dput(head(meth)) is a very large data table/listing of data by category of what I presume to be the data from the two TCGA .txt files I referenced previously. Is this the output you were expecting? On Tue, Jun 25, 2019 at 12:19 PM Rui Barradas wrote: > Hello, > > 1) That error com

Mr. Barradas, I got the same "output" as before, which is the + indicating that the expression is incomplete (according to some R users response in this chain). Should the argument perhaps be c1 = strsplit(i, split = '\\', fixed = T)[[1]] thereby eliminating the "." ? The reprex and error me

Re: [R] Output for pasting multiple vectors

Hello, Maybe with c1 = strsplit(i, split = '\\.', fixed = T)[[1]] instead of split = '.' The dot is a metacharacter that matches any character so it has to be escaped. Hope this helps, Rui Barradas Às 16:11 de 25/06/19, Spencer Brackett escreveu: c1 = strsplit(i,split ='.', fixed = T)[[1
