Any tick marks, axis labels, main and sub titles will be outside of this rectangle.Īny graphical parameter settings that you would like to be in place before fun is evaluated can be specified in the pars argument (warning: specifying layout parameters here ( plt, mfrow, etc.) may cause unexpected results).Īfter the function completes the graphical parameters will have been reset to what they were before calling the function (so you can continue to augment the original plot). The rectangle defined by x, y, size, vadj, and hadj will be used as the plotting area of the new plot. Setting vadj and hadj to (0,0) will position the lower left corner of the plot at (x,y). The default is to center a 1 inch by 1 inch plot at x,y. If x and y are given as scalars then the plot position relative to the point and the size of the plot will be determined by the arguments size, vadj, and hadj. If vectors of length 2 then they determine the opposite corners of the rectangle for the embedded plot (and the parameters size, vadj, and hadj are all ignored. Passing this list to par will enable you to augment the embedded plot.ĭetails: The coordinates x and y can be scalars or vectors of length 2. Return Values: An invisible list with the graphical parameters that were in effect when the subplot was created. # right way to add a reference line to histogram Note that, the R par() function can be used to change the color, font style. ![]() Tmp2 <- subplot( hist(tmp,xlab='',ylab='',main=''),Ĭords(0.1,0.9,'plt')$usr, vadj=1, hadj=0 )Ībline(v=0, col='red') # wrong way to add a reference line to histogram Directly by specifying the titles to the plotting function (ex : plot() ). Subplot( hist(runif(100),main='',xlab='',ylab=''), 11, 51, hadj=0, vadj=0) R par () function We can put multiple graphs in a single plot by setting some graphical parameters with the help of par () function. Install.packages("Hmisc", repo="", dep=T) ![]() Usage par (, no.readonly FALSE) (. ![]() Parameters can be set by specifying them as arguments to par in tag value form, or by passing them as a list of tagged values. A list of parameters to be passed to par before running fun. par function - RDocumentation par: Set or Query Graphical Parameters Description par can be used to set or query graphical parameters.
