Available in S-plus, also in R1.8.1?
Hello all,
I'm looking for the R-equivalent of the S-option "Connect type: half
horiz first". Link:
http://miner.stern.nyu.edu/Splus/help/guihelp/__hhelp/connect_type.htm
I'm plotting with type="s" or type="S"; this is giving me a stairstep
starting, or ending with the value on the x-axis (as documented). But, I
want the x-value in the middle of the step, like "half horiz first" in
S-plus does.
Is this possible in R?
Thanks,
Maarten

CDF plot
Dear all,
I have define a discrete distribution P(y_i=x_i)=p_i, which I want to
plot a CDF plot. However, I can not find a function in R to draw it
for me after searching R and R-archive. I only find the one for the
sample CDF instead my theoretical one.
I find stepfun can do it for me, however, I want to plot some
different CDF with same support x in one plot. I can not manage how to
do it with

questions regarding spline functions
Greetings,
A couple general questions regarding the use of splines to interpolate depth
profile data.
Here is an example of a set of depths, with associated attributes for a given
soil profile, along with a function for calculating midpoints from a set of
soil horizon boundaries:
#calculate midpoints:
mid <- function(x) {
for( i in 1:length(x)) {
if( i > 1) {
a[i] = (x[i] -
