histogram - density on y axis and restriction to interval [0, 1]
...%]). Proportions are correct
but the indication 1.4 is not usual.
v <- c(1,2,2,3,3,3,4,4,4,4,4,4,4,4,4,4,4,4,4,4)
> hist(v, freq = FALSE)
I thank you in advance for any explanation about the way to force the y
axis to restrain to interval [0,1] on an histogram.
Best regards,

access to right time unit when checking for time execution
Hello,
I really wonder how to distinguish between secs and mins in the example
below.
In other terms, how can I access the time unit in variable d ?
start1 <- Sys.time();
stop1 <- Sys.time(); d <- stop1-start1; print(d);
v<-unlist(strsplit(as.character(d), split=" ")); print(v)
Time difference of 3.024054 secs
[1] "3.02405381202698"
stop1 <- Sys.time(); d

use of ROCR package (ROC curve / AUC value) in a specific case versus integral calculation
...not possible and I have to compute the area under the curve but
I cannot find on the Web how to perform this, through an R package,
using the two vectors above, if possible (I would rather not implement
an integration algorithm).
I thank you in advance for your answer.
Best regards,
