Description Usage Arguments Details Value References

Combine MODIS files and split into species-level files.

1 2	processModis(species.col, obs.table, read.wd, write.wd, aux.wd, keep, drop, cores)

`species.col`	Character vector specifying the column that contains the species names. Will be used to split files. IMPORTANT: ebirdr generally uses file names as organizational/naming structure. It's possible that the species names do not match the file names, for instance if the analysis is using a different taxonomy than eBird. If this is the case, and if the raw MODIS files contain the OBS_ID, the this argument can be set to NULL, and a 'obs.table' passed instead. See below.
`obs.table`	Data frame with 'OBS_ID' as the first column, and the 'correct.species' that observation belongs to as the second column. If this approach is used, then 'correct.species' must be one of the values in keep. This argument can be missing if species.col is provided.
`read.wd`	Path to the read directory, where the files to be prepped are found.
`write.wd`	Path to the write directory.
`aux.wd`	Path to directory where the sample size summary file will be saved.
`keep`	Character vector of columns to keep in the output files.
`drop`	Should points that were not assigned complete MODIS values be dropped? Default is TRUE.
`cores`	How many cores to use for parallel processing.

This function works by first binding all the files together in read.wd, then dropping to all but the specified columns in keep, optionally dropping incomplete records, then splitting into species-level files and saving out.

Nothing to workspace. Saves out two files. First to aux.wd is a data frame summarizing per species sample sizes. Next are species-level csv files with matched MODIS data. Spaces in the species names will be removed.

Team eBird.
