Hello,
I'm using the package pROC in RStudio to create my ROC-curves and I have
patients in my data - healthy or sick - in the column "Status" and the value
"SUVmax" to examine it.
I used the following code:
plot.roc(daten$Status,daten$SUVmax,percent=TRUE,ci=TRUE,print.auc=TRUE,main="ROC-Kurve

have you looked at the ROCR package?
there are at least a few ways to plot multiple ROC curves with the

The info in this link suggests that plot in the pROC package can only compare

I considered that but on the list more people are likely to see it. So if they

Or if not, I'll make a reproducible example, ask the maintainers and post back

I am computing a new variable as a predictor for a label. The new variable is a

what you suggested worked out well. This code below also worked out well for

I am using Proc Npar1way with D option to get KS test statistic.

Here X is a binary dependent variable and Y is the predicted probabilities;

Well, the easiest way would be to use SAS ;-)
In R take a look at the ar() function. You can view documentation by

Many thanks for your prompt feedback. You were right about the data.

If this happens the map seems alright using GIS programs because you can

Hi All,
I'm working with some SAS code to analyze an experiment set up as follows:
66 subjects (colonies) treated with a random treatment (1-8) and measured at
three time points.
The data structure looks like:
input colony tmt y1 y2 y3;
y=y1; date=*1*; output;
See the contents function in the Hmisc package.

Here is another option: all.equal() is more general, the sapply()

that maybe a few elements are different (e.g., you have two data sets
and are not sure which is more recent).
y <- x <- iris # x & y copies of iris

one would with the SAS procedure PROC COMPARE?
Any help on this would be greatly appreciated.
