Create rglactions list, suitable to be passed as parameter to vis functions.

Usage

rglactions()

Value

named list, an example rlgactions instance that will save a screenshot of the plot produced by the vis function in the current working directory (see getwd), under the name 'fsbrain_out.png'.

Note

List of all available rglactions: (1) snapshot_png=filepath takes a screenshot in PNG format and saves it in at filepath. (2) trans_fun=function uses the transformation function trans_fun to the data before mapping data values to colors and plotting. Popular transformation functions are limit_fun, limit_fun_na, and clip_fun. (3) text=arglist calls text3d with the given args after plotting. (4) snapshot_vec=filepath takes a screenshot in vector format and saves it in at filepath. You also need to set the format via snapshot_vec_format, valid entries are one of "ps", "eps", "tex", "pdf", "svg", "pgf" (default is 'eps'). This is experimental and may take a while.

Examples

   rgla_screenie = list('snapshot_png'='fsbain_out.png');
   rgla_screenie = rglactions();   # same as above
   rgla_vec_scr = list('snapshot_vec'="~/fsbrain.pdf",
     "snapshot_vec_format"="pdf");
   rgla_clamp = list('trans_fun'=clip.data); # old style
   rgla_clamp = list('trans_fun'=clip_fun(0.05, 0.95)); # new style
   rgla_clamp = list('trans_fun'=clip_fun());            # equivalent.
   rgla_limit = list('trans_fun'=limit_fun(2,5));
   rgla_ls = list('trans_fun'=limit_fun_na(2,5), 'snapshot_png'='~/fig1.png');
