Hello,
I have a MacBook Air M1
I newly installed R and R studio. Also fcaR(formal concept analysis for R).
I followed fcaR via the help files.
Finally I did fc_planets$standardize() : worked.
Then: fc_planets$concepts$plot()
Warning message:
You have not installed the 'hasseDiagram' package, which is needed to plot the
lattice.
So, I installed:
install.packages("hasseDiagram”)
Then: library("hasseDiagram”)
Finally:
fc_planets$concepts$plot()
It gave:
Warning in install.packages :
dependencies ‘Rgraphviz’, ‘graph’ are not available
trying URL
'https://cran.rstudio.com/bin/macosx/big-sur-arm64/contrib/4.4/hasseDiagram_0.2.0.tgz'
Content type 'application/x-gzip' length 37789 bytes (36 KB)
==================================================
downloaded 36 KB
No idea what to do to get a plot of the lattice.
Any help would be appreciated.
Peter
