[R] Error running help.search("keywords")

[Yo Gmail]

Hi,

When running help.search(“linear algebra”) or any other valid search keyword the following error is being returned:

Error in help(db[i, "topic"], package = db[i, "Package"], lib.loc = lib,  : 
  'topic' should be a name, length-one character vector or reserved word

I have not installed the optional packages neither Tcl/Tk nor Texinfo.

Any ideas what the error could be, what can I do to fix it?

My sessionInfo() is:
