The key is that you want to use the same curl handle

Generally the GUI's handle this with 'save as...' functions. but if you are in
a console session then consult:

Hi Raimund,
You can use spg() in the BB package. This requires that you have a projection

Dear R users,
I am trying to estimate a panel data model using rqpd(). I also estimated
the same model using rq() and dummy variables for the groups. The
coefficient estimates differ substantially between the two approaches
(rqpd() produces substantially larger coefficients).
Should the two appro

Suppose I want the output as "Trial and a sheet" without quotes
x=c("a", "b", "c")
print("Trial and x[1] sheet")
Getting "Trial and x[1] sheet"
Can anyone help?

Yes. Itâs a part of a particular function. It is required thing to be done in
R, otherwise we have to be done manually and that will take time.

Hello
I am not really a statistic person, so it's possible i did something completely
wrong... if this is the case: sorry...
I try to get the best GLM model (with the lowest AIC) for my dataset.
Therefore I run a stepAIC (in the "MASS" package) for my GLM allowing only
two-variable-interactions.
Dear all,
I have two different data frames, that have two common variables: date and
sample. Here is a small extract of both of them

Dear Luigi,
Here's an option:
boxplot(x, boxcol="white", whiskcol="white",medcol="white",staplecol="white")
abline(h=c(-1,0,1))
grid(NA, 4, lwd = 2)
boxplot(x,add=T)

There is a "panel.first" argument that can be used with many different
types of plots.
plot(x, panel.first=abline(h=-3:3, lty="dotted", col="gray"), pch=16,
col="red", cex=3)
# red big plotting characters: to show that ablines are drawn before plotting
# the result is different from doing the plot
Hello,
1) Instead of computing TFrequency and TVolume like you have, try the
following.
TF <- with(Frequency, ave(Frequency, Specie, FUN = sum))
TV <- with(Volume, ave(Volume, Specie, FUN = sum))
Fi <- with(Frequency, Frequency/TF)
Vi <- with(Volume, Volume/TV)
Importance <- Fi*Vi/sum(Fi*Vi)

Hi Thomas
thx, already the e <- parse(text="df$str==12")[[1]] is nice. So I have
not to call parse in my function! (The function is called very often, so
it makes the program much faster.)
And eval(bquote(function(df) b<-.(e))) is great! That's exactly what I
was looking for.
