1.	What does the ‘pch’ option to par() control?(a) the size of the plotting symbol in a scatterplot(b) the line width in the base graphics system(c) the orientation of the axis labels on the plot(d) the plotting symbol/character in the base graphics systemThis question was addressed to me during an online exam.My doubt stems from Exploratory Data Analysis topic in chapter Profiling, Simulation and Data Analysis of R Programming
Answer» Correct answer is (d) the plotting symbol/character in the base GRAPHICS system Easiest explanation: R makes it easy to combine multiple PLOTS into one overall GRAPH, USING either the par ( ) or layout( ) FUNCTION.
