[R-sig-Fedora] Cannot install knitr

[Paul Smith]

Dear All,

I am trying to install the package

knitr

but getting the following error:

----------------------
Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared object '/usr/lib64/R/library/stringi/libs/stringi.so':
  libicui18n.so.56: cannot open shared object file: No such file or directory
Error : unable to load R code in package ‘knitr’
ERROR: lazy loading failed for package ‘knitr’
* removing ‘/usr/lib64/R/library/knitr’
* restoring previous ‘/usr/lib64/R/library/knitr’
----------------------

I suppose that the problem is that knitr expects

libicu-56

installed, but it is

libicu-57

that is installed.

Any help?

Thanks in advance,

Paul
