Dear all,

I have been trying to load the package 'largeVis' but despite I do not receive any error message when installing it, I keep getting  the following error when loading it in my working directory:

require("largeVis")

Loading required package: largeVis
Loading required package: Matrix
Error : object ?opticsXi? is not exported by 'namespace:dbscan'

As suggested in other posts with a similar error message (but for different packages), I have already tried to uninstall R, restart my machine and install the newest version of R available, however this does not seem to help solving the issue.
Also, after loading 'dbscan', when typing 'dbscan:::opticsXi', I get:

dbscan:::opticsXi

Error in get(name, envir = asNamespace(pkg), inherits = FALSE) :
 object 'opticsXi' not found

Does anybody have any suggestion on how to solve this issue?
