read_sumstats {MungeSumstats} | R Documentation |
Determine summary statistics file type and read them into memory
read_sumstats( path, nThread = 1, nrows = Inf, standardise_headers = FALSE, mapping_file = sumstatsColHeaders )
path |
Filepath for the summary statistics file to be formatted. A dataframe or datatable of the summary statistics file can also be passed directly to MungeSumstats using the path parameter. |
nThread |
Number of threads to use for parallel processes. |
nrows |
integer. The (maximal) number of lines to read.
If |
standardise_headers |
Standardise headers first. |
mapping_file |
MungeSumstats has a pre-defined column-name mapping file which should cover the most common column headers and their interpretations. However, if a column header that is in youf file is missing of the mapping we give is incorrect you can supply your own mapping file. Must be a 2 column dataframe with column names "Uncorrected" and "Corrected". See data(sumstatsColHeaders) for default mapping and necessary format. |
