Using files as connections
...line if the connection is open, but presented with
a closed connection it will open it, start from the beginning, and close
it when finished.
In the code that follows I tried to open the file before reading but
apparently without success, because the result was repeated copies of the
first line:
flines <- 107165
slines <- 100
selected <- sort(sample(flines,slines))
strvec <- rep(??,slines)

for (iline in 1:slines) {
isel <- isel + 1
cline <- readLines(?c:/data/perry/data.csv?,n=1)
if (iline == selected[isel]) st...

Thanks in anticipation,

Controlling the length of line with abline(lm())
Hi
I just realized that when I use linear regression to draw a line through my
data points with something like the following:
abline(lm(y ~ x))
the length of the line is infinite, i.e., the line goes beyond the smallest
and the largest data values. This seems not very right to me (not to mention
it looks unaesthetic). I do not mean to imply that the straight-line
behavior of my system is
