I have a relatively large-ish (>4,000 records) dataset of species records that needs to be mapped in R, however the only spatial information with them are 6 figure Ordnance Survey’s National Grid (NGR) format grid references (e.g. SD311124, see also A beginners guide to finding grid references). The file format is CSV.
How can I get R to plot the points with this information?
Is there a better way to do it within R rather than bulk converting and adding lat/long coords to the spreadsheet before loading it into R?
I know how to do this in QGIS, but my supervisors would like it in R instead!
