Dear R People:
I am trying to replicate a cool example that I saw on the R-bloggers some

Greets,
I'm using a data frame that looks like:
head(pr2)
X1 X2 X3 X4Y fit res
1 44 33.2 5 30 41.2 39.22201 1.977991
2 43 33.8 4 41 31.7 38.48476 -6.784761

Hello,
I am trying to decide which package to use to calculate the non-parametric
Sen's Slope for identifying trends in rainfall data (determine the slope
between all pairs of points and take the median of those slopes). I have
found three packages that output Sen's: zyp, wq and fume. The
Hi,
What is the result of:
