  • 0

I have been working with the minfi R package. All the functions used to work fine in it, when I worked with another computer. I installed minfi 2 days back in my own laptop. Most of the functions work fine, but when i use a command which has a function preprocessSWAN(), I get the error

Error: could not find function ¨proprocessSWAN¨

I get this error everytime I work with this function only, in the midway of running my analysis.

I had also tried reinstalling minfi to see if something had gone wrong during the installation. But even after reinstalling, I find the same problem. This function works fine on my windows and also the other computer.

Can anyone tell me why am i having this problem in my ubuntu ? And what should I do to make it work?

    I would suggestion checking that you have the same version on each machine. Look at the NEWS for the package, suggests that preprocessSWAN() is fairly new. So, look at:

    library(minfi)
packageVersion("minfi")

    on each machine you own. I realise that you updated your package, but your really need to check that all your bioconductor packages are up to date. So, try something like:

    url='http://bioconductor.org/biocLite.R'
source(url)
update.packages(repos=biocinstallRepos())

    Also, are you running the same version of R? Type version on both machines. To get the same bioconductor version you will (I think) need the same version of R. So you may need to upgrade R.
