Is it possible to use package semPlot with R 3.6.2?

I upgraded R to version 3.6.2 and have discovered that package semPlot will not work. It installs without any problems, but when I try to load it I get the message,

Error: package or namespace load failed for ‘semPlot’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ‘ggm’

I then tried to install ggm but get the following warning and error:

Warning in install.packages : dependency ‘graph’ is not available

There is a binary version available but the source version is later: binary source needs_compilation ggm 2.3 2.5 FALSE installing the source package ‘ggm’ trying URL 'https://cran.rstudio.com/src/contrib/ggm_2.5.tar.gz' Content type 'application/x-gzip' length 109414 bytes (106 KB) downloaded 106 KB

ERROR: dependency ‘graph’ is not available for package ‘ggm’ removing ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library/ggm’ Warning in install.packages : installation of package ‘ggm’ had non-zero exit status"

I then tried to install graph, but it says:

package ‘graph’ is not available (for R version 3.6.2).

I wondered if anyone else had experienced this problem, and had any solutions so I can load semPlot with R 3.6.2?

Many thanks.

Solution

  • I also have R 3.6.2 and get all errors you get. But when I try to install the semPlot package from GitHub, it works fine, as follows:

    install.packages('devtools')
library(devtools)

install_github('SachaEpskamp/semPlot',  dependencies = T)
library(semPlot)

    Please not that I tried the cran/semPlot repository but didn't work for me, whereas SachaEpskamp/semPlot does.

    Hope you get it working.
