Dear list, I ran into a strange behaviour of the pnbinom function - or maybe I just made a stupid mistake. First thing is that pnbinom seems to be very slow. The other - more interesting one - is that I get two different curves when I plot the estimated density and the density given by pnbinom. Shouldn't it be the same? This is only the case, I think, if I use the parameter size = 1. I

...Q/R-FAQ.html#How-do-I-convert-factors-to-numeric_003f and history from the list but it is impossible for me to convert the data to numeric without rounding or ranking the values. E.g.: Simply using as.numeric puts the values into ranked classes as explained in the manual, As.numeric(as.character(probas)) as well as as.numeric(levels(probas$forecast_probs))[as.integer(probas$forecast_probs)] return ?NA? for every row. Anyone any idea? --

Dear all, First I apologize if my question is quite simple, but i'm very newbie with R. I have vectors of the form v = c(1,1,-1,-1,-1,1,1,1,1,-1,1) (longer than this one of course). The elements are only +1 or -1. I would like to calculate : - the frequencies of -1 occurences after 2 consecutives -1 - the frequencies of +1 occurences after 2 consecutives +1 It looks probably something like

Hello all R users, My simulation function works correctly, but I have problems with plot function. You will find the following code using it. Thank you for your help ##################################################" simulation <- function(k, n){ conc <- seq(0,10,by=0.5) #choixg <- seq(1, length(conc)) choixg <- rep(0,length(conc)) for (i in 1:length(conc)){ choixg[i]

Dear Rusers, I tried to implement a function comparing mean scores between one subject (the patient) and a group a control subjects. The function returns attended results, but I also obtained the following warning : Warning message: the condition has length > 1 and only the first element will be used in: if (substr(fp, 1, 1) == "<") fp else paste("=", fp) Maybe

I have succeded in defining the cdf of the generalized beta of the second kind, eg. pgbeta2 <- function(quint,b,a,p1,p2) { integrate(function(x) {exp(log(a)+(a*p1-1)*log(x)-(a*p1)*log(b)-log(beta(p1,p2))-(p1+p2)*log(1+(x/b)^a))},0,quint)$value } but I'm facing problems with the quantile function. I tried something like qgbeta2 <- function(proba,b,a,p1,p2) { optimize(function(z)

Hi all R users, I have problems with my second loop for drawing the three curves in the same graphic. I need help please Thank you in advance ######################################################################### simulation <- function(k, n){ conc <- seq(0,100,by=0.5) #choixg <- seq(1, length(conc)) choixg <- rep(0,length(conc)) for (i in 1:length(conc)){ choixg[i] <- (k

Happy New Year, r-helpers! I am using lowess to smooth a scatter plot, xx<-lowess(xinput,f=.04) #defaults for other args followed by turnpoints(xx$y) #defaults for other args I plot the smoothed result as well as turnpoints (using yy$tppos) on top of raw data plot. Result is exactly as expected, graphically. For another purpose, I calcuate the difference between turnpoints (representing

Hello all R users, I would like to add another loop to my following R code ( it works for the moment correctly) , which will be able to me to vary n (see the code) from 1 to 4 or 5. And I also would like apply the plot function in this case, eg all four or five figures in the same graphic (n= 1, 2, ..., 4 ou 5) I have tested one, but unsuccessfully. I need you to solve this problems Thank you

I encountered this error/warning (I don't know) and I saw in http://lists.samba.org/archive/samba/2005-May/105124.html that jerry was aware of the problem. Should I worry about it or ignore this message ? Thanks.

The documentation shells created by the utility functions for classes and methods contain section "Methods". Due to a slight difference in the layout and the underlying Rd code, function signatures are wrapped on the following line (if necessary) in the "methods" section in a class description (xxx-class.Rd) but not in xxx.-methods.Rd. As a result long signatures may

>From the manpage: --csum-length=LENGTH By default the primary checksum used in rsync is a very strong 16 byte MD4 checksum. In most cases you will find that a trun- cated version of this checksum is quite efficient, and this will decrease the size of the checksum data sent over the link, mak- ing things faster. You can choose the

Dear R-users, I have problems with printing Central European (CE) characters (e.g. {\H o} and {\H u}) in graphics made by R. After executing the following code I can see the CE characters with gv on my screen, but I cannot print them on a postscript printer. > postscript(file="proba.ps",enc="ISOLatin2.enc") > plot(0:15,0:15,type="n") > grid(15,15,lty=1)

Hello R Community, I've been working on a project that uses pre-made C++ libraries (using STL) in R and build a package. However, I've been getting an unusual segfault that I'm unable to trace its origin. After many attempts of debugging using gdb, commenting out parts (or all of my code) and valgrind, I'm unable to make heads or tails about what I'm doing wrong. In fact, when
