I used the AR modelling written for R (S) on blood pressure and heart rate signals. I used 60 one second samples and a model order of 20. I used the "ar" finction in the "ts" package. Given that blood pressure is measured in mmHg would the spectral density (on the graph displayed be [mmHg]sq/Hz ? And the heart rate is measured in Beats Per Minute (bpm) - so would the

Dear R-List members, I want to check if a set of measurements follows better a gamma or a lognormal distribution (see data below). Using shapiro.test I can test for normality (shapiro.test(log (Lt)). To test for gamma (and normal) distribution I would use ks.test but I need to specify its shape and scale. How should I calculate these values in R? I tried > Lt.fit <- glm(Lt ~ 1,

Short example: > str(d <- data.frame(a = I(letters[1:5]))) `data.frame': 5 obs. of 1 variable: $ a:Class 'AsIs' chr [1:5] "a" "b" "c" "d" ... > str(d[TRUE,,drop = FALSE]) `data.frame': 5 obs. of 1 variable: $ a: chr "a" "b" "c" "d" ... The real problem about this is, that as soon

I would want to know if it's possible to plot two histograms on the same graphic in order to compare the bins one to one, like a Excel graphic. If it is possible can you help me to do it, because I don't know the exact R-commands.

In several places, we have the convention that col = NA means `` don't draw '', e.g. for points() or rect(). For col = <vector> this only works when the vector is integer (numeric), but not in other cases. I think this is a bug, even though not in the strict sense, since we don't seem to claim it should work.. Example: plot(1:10, col = c(1:4,NA,NA,4:1)) ## fine
