| r2gmt {gmt} | R Documentation |
This function handles data that will be annotated on a GMT map, writing them to a temporary file. Although it is an internal function, users may find it handy for some tasks.
r2gmt(x, outfile, append=FALSE)
x |
data frame, matrix, or filename containing the data to be written to a temporary file. |
outfile |
filename where the data will be written in GMT format, tab-separated without header. |
append |
whether data should be appended to an existing file, separating segments with ">" lines. |
If x is a filename, the data should be tabular with or without
a header, separated by commas or whitespace. The first line is
interpreted as header if the first non-whitespace character is not
minus, point, or number.
The data frame that was written to outfile.
This function is primarily an internal function, but users may find it handy for their own plotting functions.
