Hi everyone,
Is there any counter function in R for the following purpose:

As I would like to know how many zeros, ones, and twos in each row of x?

avoiding reinstall already installed library
Dear R-experts,
I am installing new libraries using
install.packages("ggplot2",dependencies=T).
But I perceive that many dependencies are already installed. As I am using
a low-band internet, how can avoid reinstall installed libraries?

AUC / ROC for presence only.
Dear all,
I have a probability of presence of distribution of a species of interest
(varying from 0 to 1 in continuous form) and I have a set of points
where I know that species really occurs. But I don´t have points of absence.
So, for each true presence I know the estimated presence.
I would like to know how can I compute AUC, taking account these
Available data.
Best wishes,

I have a code like

Now I would like to plot y1 and y2 on the same graph, with its two scales
(y1 on left and y2 on rigth side).

updating columns using other column as reference
Dear R-gurus,
Just supose I have a dara.frame that looks like
myDF<-read.table(stdin(),head=T,sep=",")
codID,namesp,k1,k2,k3,k4
1,spA,2,5,6,3
2,spB,4,5,4,6
3,spC,2,1,5,6
4,spC,5,4,3,2
5,spD,1,2,3,4
6,spE,2,4,3,1
I need to update the columns k1-k4 with the namesp, but
considering the math between Kx and codID.
My desired output must looks like:
codID,namesp,k1,k2,k3,k4
