Hello,
I am having issues running my SNP dataset through the poppr() function. The dataset contains 995 individuals across 6 populations and 10736 SNPs. On my local machine (16Gb RAM) the function runs for ~10min and lists out all population names in the console before returning "Error: vector memory limit of 16.0 Gb reached, see mem.maxVSize()".
I figured this was a memory issue, so I then tried this on RStudio servers, first with 60Gb and then 500Gb RAM. The function similarly lists out all populations before aborting R: "the R session was abnormally terminated due to an unexpected crash." Each time I increased the RAM the function ran for a longer duration, but the outcome was the same.
Could this be something other than a memory issue? One problem with my dataset is a relatively high amount of missing data (~60% call rate overall). Could this be interfering with one of the calculations in the function?
Appreciate any assistance,
David
