mt_heatmap_ggplot
plots high resolution raw trajectory maps. Note that
this function has beta status.
mt_heatmap_ggplot( data, use = "trajectories", dimensions = c("xpos", "ypos"), use2 = "data", facet_row = NULL, facet_col = NULL, ... )
data | a mousetrap data object created using one of the mt_import
functions (see mt_example for details). Alternatively, a trajectory
array can be provided directly (in this case |
---|---|
use | a character string specifying which trajectory data should be used. |
dimensions | a character vector specifying the trajectory variables used to create the heatmap. The first two entries are used as x and y-coordinates, the third, if provided, will be added as color information. |
use2 | an optional character string specifying where the data that
contain the variables used for faceting can be found (in case these
arguments are specified). Defaults to "data" as |
facet_row | an optional character string specifying a variable in

facet_col | an optional character string specifying a variable in

... | arguments passed to mt_heatmap_raw. |
mt_heatmap_ggplot
wraps mt_heatmap_raw and returns a ggplot
object containing the plot. In contrast to mt_heatmap_plot
plots
created by mt_heatmap_ggplot
can be extended using ggplot's +
operator. For further details on how the trajectory heatmaps are constructed,
see mt_heatmap_raw.
