when running ParticleSizer (https://imagej.net/ParticleSizer), histogramms representation fails with the last version of R.exe (v4.0.0)
Downgrading the R.exe from v4.0.0 to v3.2.0, the post-processing succeed !
Maybe a bug or an incompatibility between the last release of the plugin and the R.exe ones has been introduced.
I am not a specialist in both of them (just a new user). Developers, feel free to investigate the problem.
