extractMRFSS {fishmethods} | R Documentation |
MRFSS intercept and catch/effort data in SAS transport files (.xpt) are extracted using
package foreign
and are saved as .csv files under data and year-specific subdirectories.
extractMRFSS(indir = NULL, outdir = NULL, type = NULL, state = NULL, styr = NULL, endyr = NULL)
indir |
the path and directory (in quotes) under which the SAS transport files are stored. |
outdir |
the path and main directory (in quotes) under which data- and year-specific subdirectories will be created and .csv files will be stored. |
type |
the type of data to extract. 1 = raw intercept data, 2= catch/effort estimates. |
state |
the state code(s) designating which state(s) data to extract. If multiple states, separate state codes with commas within the
concatentation function. If data from all states are desired, do not include the state= argument. State codes are
found on the MRFSS website. |
styr |
the starting year of data to extract. |
endyr |
the ending year of data to extract. |
Download the zipped intercept data and catch/effort estimates from the MRFSS website http://www.st.nmfs.noaa.gov/st1/recreational/index.html. Unzip/extract the
SAS transport files (.xpt) to the indir
directory. Using this function, specify the indir
and outdir
directories, which data type to extract, the state code(s),
and the starting and ending years (from .xpt files) of data to be extracted. If the outdir
directory is not specified, the files will be stored under the
indir
directory.
Raw intercept data and catch & effort estimates saved as .csv files.
