[R] plot vs print ??

[Joshua Wiley]

Hi,

It really depends, but almost always to plot a graph you would use
plot() (or some similar graphing function).  print() is usually more
for displaying data in the console, not graphically.  There are some
cases (e.g., inside a for loop), where you need to wrap the call to
plot (or similar graphing function) in print() (lattice graphics is
probably the most common example here).  Here is an
example/demonstration of plot() and print() in the context of a
histogram (which was calculated and saved into an object called 'x'):

## do histogram calculations but do not plot
x <- hist(rnorm(1000), plot = FALSE)

## print() just shows you the data
print(x)
## put data in a graph
plot(x)

## but you could also just use hist() without plot() or print()
hist(runif(100))

HTH,

Josh
