[R-pkg-devel] Finding dependencies (Was: problem with submitting to CRAN (windows))

[Krzysztof Bartoszek]

Looking manually the chain is actually different
mvSLOUCH <--- TreeSim <-- geiger <-- phytools <-- gtools
TreeSim does not import anything directly from phytools

But given the amount of packages that depend on gtools and seeing how long the above path is, I wonder how many packages on CRAN are experiencing some sort of issues.
Best wishes
