two questions about character manipulation
Dear all,
I want to manipulate a character string such as
ex<-"cbind(data$response1,data$response2)"
in R in two ways:
1) extracting the "response1" portion of ex
2) replacing "$" with "."
I am wondering that is it possible efficiently doing these in R?
Best

Plotting confidence intervals of two response on same graph (panel).
Hello!
I would like to draw a graph like the following:
http://www.optics.rochester.edu/workgroups/cml/opt307/spr04/pavel/plot_small.jpg
Aim is to plot confidence intervals of treatments for X(=response1) and
Y(=response2) axis simultaneously to visualize aggreement of confidence
interval for two responses.
Can anyone please provide me some direction to start with?
Thanks!

How to calculate the area under the curve
Hi all,
I would like to calculate the area under the ROC curve for my predictive
model. I have managed to plot points giving me the ROC curve. However, I do
not know how to get the value of the area under.
Does anybody know of a function that would give the result I want using an
array of specificity and an array of sensitivity as input?
Thanks,
Olivier
