examples cannot be loaded on Mac

[EmmiKurosawa]

I installed everything that was on the 2.2 Mac OSX section except the optional pndoc (I use R studio). Now I am trying to load the examples so I can learn how to use MixSIAR. However, None of the following script worked. Please advise.

browseVignettes("MixSIAR") No vignettes found by browseVignettes("MixSIAR")

find MixSIAR directory

mixsiar.dir <- find.package("MixSIAR")

folder with script files

paste0(mixsiar.dir,"/example_scripts") [1] "/Users/gamba/Library/R/4.0/library/MixSIAR/example_scripts"

run Geese example

source(paste0(mixsiar.dir,"/example_scripts/mixsiar_script_geese.R")) Error in eval(ei, envir) : lazy-load database '/Users/gamba/Library/R/4.0/library/MixSIAR/R/MixSIAR.rdb' is corrupt In addition: Warning message: In eval(ei, envir) : internal error -3 in R_decompress1
