Hello,

I am using the package restrSiteUtils version 1.2.8. Until now, everything was fine but now when I want to start working with the package, following error arise:

> library(restrSiteUtils)
Error: package or namespace load failed for ‘restrSiteUtils’:
 object ‘ifelse’ is not exported by 'namespace:IRanges'

I have just recently updated R and all Bioconductor packages that I use. Is IRanges package changed somehow so exporting ifelse doesn't work? And does anybody have an idea how could I overcome this error so I could use my desired package?

Thanks in advance for any advice

This is a question you should be asking of the maintainer for restrSiteUtils, which isn't a Bioconductor package. This site is intended to support Bioconductor packages, not other packages that may make use of some Bioconductor packages.

You might point out that IRanges no longer defines nor exports ifelse, but instead ifelse2:

    replace ifelse generic and methods with ifelse2 (eager semantics)
