write.fits: Write data to a fits file
In oczoske/slacR: R-package to measure v and sigma from VIMOS IFU cubes

Description Usage Arguments Details Value Author(s) See Also Examples

This is a very basic function to write some data from R to a fits file. The function is a wrapper for the C program R2fits.

1	write.fits(x, outfile, nx, ny, na.val = 0)

`x`	The input data. This can be a vector of length (at least) nx x ny, or a matrix with dimensions nx and ny.
`outfile`	The name of the fits file to be written. To force overwriting an existing file us a leading "!".
`nx, ny`	The x and y dimensions of the image to be written. These have to be specified if `x` is a vector. If `x` is a matrix, its dimensions are used. `nx` and `ny` can also be vectors giving the world coordinates of the image pixels. In this case, the number of pixels in each direction is computed automatically.
`na.val`	Numerical value to replace `NA` in the input data `x`.

The output created by R2fits and hence by this function is a very basic fits file whose header only contains the image dimensions and the date of writing. Any extra information on the data will have to be added automatically.

None.
