I'm trying to use tximport with salmon quantifications. Initially I had some problems installing tximport because of the version of R (3.3.1) and bioconductor (3.2) installed on our Rstudio server so (while I wait for the guys who maintain that to fix it) I figured I'd install it directly from the bioconductor github site:


This went just fine, but when I then try to load some data I get the following error:

tximp_files <- file.path(exp[[3]], "quant.sf")
txi <- tximport(files, type="salmon", tx2gene=t2g)

reading in files with read_tsv

Error in guess_header_(datasource, tokenizer, locale) : basic_string::resize

tximport(files, type = "salmon", tx2gene = t2g)

The quant.sf data were generated with salmon 0.5.1, the file paths are correct and the files look like:

If you already have mis-matched R and Bioconductor versions (R-3.3.1 should be running BioC 3.4, not Bioc 3.2), the fix is probably not to install devel versions of other packages.

Anyway, the error you are getting is from Hadley's readr package, which is not a Bioc package at all. You can always use read.table instead, or alternatively you could install the release version of readr, which is certainly working for me.

Can you post the error when installing with biocLite()? This is the installation route that we commit to provide support for, going off that trail you're a bit on your own.

It's just a warning because of the version mismatch and a failure to install. Looks like I'll just have to suck it up and wait for the sys-admins to upgrade the bioconductor version tot he right one...

Yeah, Bioc 3.2 is from October 2015, so is 1.5 years out of date. tximport was introduced in Bioc 3.3 in April 2016. This information is on the package landing page:
