similar to: Add on argument in seq()

Hi. I have a problem with the default behavior of sample(), which performs sample(1:x) when x is a single value. This behavior is well explained in ?sample. However, this behavior is annoying when the number of value is not predictable. Would it be possible to add an argument that desactivates this and perform the sampling on a single value ? Examples: > sample(10, size = 1, replace = FALSE)

Thanks for your answer. The rational behind my proposal is why taking "from" when length.out=1, more than "to" or "NA", or " integer(0) " ? This question seems basic. But is is not in certain situations, like when length.out = unpredictable positive integer. And I haven't found in ?seq() the particular behavior of this function when length.out = 1.

It is a sequence starting at *from* and ending wherever the other arguments cause it to end. A sequence

Regardless of the value of the other arguments, the first element in the output of seq() is _always_ `from`.

Millot, I think the problem with that is that what you propose isn't a sequence starting at from in any meaningful way, and thus does not satisfy the contract of the seq function.

Dear all, Sorry to bother you, but I didn't find the solution in the R-help archive. I would like to change the thickness of stripes inside the barplot. Is there any solution to do that when using the barplot() fuction and the density option ? Or is there any other function ? Thanks very much for your help. Best regards. Gael.

Hi, Special behavior of sample(x, ...) when length(x) is 1 is of course a bad feature. I think it pre-dates sample.int() which is what people should use these days if they want the behavior of sample(x, ...) when length(x) is 1. And because we now have sample.int(), this feature could in theory be removed from sample(). Unfortunately this would break a lot of existing code so a warning or some

Hello. I am probably wrong... I am wondering if it could have a mistake in the code of the ansari.test function. For me, it seems that the function do not recover the p value at the correct side of the normal law N(0, 1) when it use the normal approximation (presence of ties) in a one tailed test. Exemple : quanti<-c(197, 205, 228, 234, 237, 195, 233, 226, 244, 227, 259, 185, 198, 253, 207,

Dear all, May I suggest to add an example in the help page of the colors() function ? The following code could be useful to easily choose any color from colors() : ## Millot G.

Something cool

Hi, I'm trying to use the "usr" argument but I see no effect of this option on my plots. For example: > par(usr=c(0,4,0,4)) > plot(1,1) This plots one point fine, but the coordinates of the plotting region are not those that I specified using par()... I can check this with > par("usr") [1] 0.568 1.432 0.568 1.432 What can I change in order to have this

Hello, I would like to write in a variable the following string : Hello "World" If I do cat("Hello ","\"World\""), I have the good result on the screen but it can not be affected to a variable. If I do the same thing with paste paste("Hello ","\"World\"") it does not work since \" seems to be not recognized. So what
