For "plot()" function kindly refer to the following example for adding title and label -
plot(1:10, main = "Example plot", xlab = "X values", ylab = "Y values")
For "ggplot()" function kindly refer to the following for the same -
library(ggplot2)
ggplot(as.data.frame(matrix(1:20,nrow = 10,ncol = 2))) + geom_point(aes(x=V1,y=V2))+labs(x="X label", y="Y label", title="Plot title")
ggplot(as.data.frame(matrix(1:20,nrow = 10,ncol = 2))) + geom_point(aes(x=V1,y=V2))+labs(x="X label", y="Y label", title="Plot title")
In the "plot()" function, parameters "xlab", "ylab" and "main" are used to add axis labels and title respectively, whereas in "ggplot()" we obtain labels and title by making use of "labs()" function as shown above.
