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.
