how to put two figures in one plot R code example

Example 1: two plots side by side r

par(mfrow=c(1,2))    # set the plotting area into a 1*2 array
barplot(max.temp, main="Barplot")
pie(max.temp, main="Piechart", radius=1)
par(mfrow=c(1,1))

Example 2: par in r

par(mfrow=c(1,1))

# make labels and margins smaller
par(cex=0.7, mai=c(0.1,0.1,0.2,0.1))

# define area for the plot
par(fig=c(0.1,0.7,0.3,0.9))

# define area for the boxplot
par(fig=c(0.8,1,0,1), new=TRUE)
