Does "sink" stand for anything?
Hello Everyone,
Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.
One function that has me stumped is "sink." Can anyone tell me if this stands for something?
Thanks,
Paul

[FORGED] Error occurring in "emmeans" package for the two data sets I used. Please help.
Thanks for your kind reply. Problem is solved. However, it's "confidence
interval / treatment comparison plot" is not taking main title. And the
fonts of axes labels can not be changed using 'cex' parameter. I will
appreciate if you could help in this matter too.

Splitting a set of vectors in a list
I have a set of character vectors of uneven length
that I have stored in a list. I can easily enough get
any column of them using lapply but what I want is to

kind of brute force looping approach I have drawn a
blank.
Would somebody please suggest something? Thanks

Different symbols for select points
Dear R users,
I hope you can help me as you have done before.
I was wondering if I can make some of the points on my graph a different colour and symbol? Some of my soil samples are enriched and I wanted them to be shown with a red triangle and the samples which are not enriched I wanted to show with a blue square. I can't seem to find a way of doing this if there is a way?

REML option in gstat
Hi, please help!!
I've been trying to fit variogram models using the REML method in the gstat
package. Every time the Windows GUI crashes. For example
library(gstat)
data(meuse)
x <- variogram(zinc ~ 1, ~x + y, meuse)
v <- vgm(140000, "Sph", 800, nug = 10000)
plot(x, model = fit.variogram(x, model = v, fit.method=5))
Other fit methods are non problematic (eg. fit.method=7
