plot.bvar_irf {BVAR}  R Documentation 
Plotting method for impulse responses obtained from irf.bvar
.
Impulse responses of all or a subset of the available variables can be
plotted.
## S3 method for class 'bvar_irf' plot( x, vars_response = NULL, vars_impulse = NULL, col = "#737373", area = FALSE, fill = "#808080", variables = NULL, mar = c(2, 2, 2, 0.5), ... )
x 
A 
vars_impulse, vars_response 
Optional numeric or character vector. Used
to subset the plot's impulses / responses to certain variables by position
or name (must be available). Defaults to 
col 
Character vector. Colour(s) of the lines delineating credible
intervals. Single values will be recycled if necessary. Recycled HEX color
codes are varied in transparency if not provided (e.g. "#737373FF"). Lines
can be bypassed by setting this to 
area 
Logical scalar. Whether to fill the credible intervals using

fill 
Character vector. Colour(s) to fill the credible intervals with. See col for more information. 
variables 
Optional character vector. Names of all variables in the
object. Used to subset and title. Taken from 
mar 
Numeric vector. Margins for 
... 
Other graphical parameters for 
Returns x invisibly.
