Dear HelpeRs,
Given:
x - rnorm(50)
y - rnorm(50)
plot(x,y)
abline(lm(x ~ y))
Is there a way to plot just a portion of the line? Say for values of x
2.0 or x -2.0 and x 4.0. (Still fitting all the points.)
Thank you,

As requested:
The alignment problem came from calling format many times. Marc
Schwartz suggested a solution of putting my results in a vector and
then formatting. As I understand it the problem is that fixed-width
fields are only available from sprintf, while comma delineation is
only available
Many thanks to Marc Schwartz who helped me work through this problem

Hello,
For numbers in the range 100 to 100,000,000 I'd like to decimal align
a right-justified comma-delineated column of numbers, but I haven't
been able to work out the proper format statement. format(num,
justify=right, width=15, big.mark=,) gets me close, but numbers
larger than 1,000,000
