i've search the email archives, searched the documention of various map packages and done an R-site search, but have been unable to find direct resources for creating maps of the US that are colored or annotated or ... by zipcode data. For example, create a map of the US and color each zipcode region by its population using two vectors z,p containing the zipcode and population,

Hello I would like to see the algorithm that R uses to generate density functions for several distributions (i.e. Normal,Weibull, etc). I tried: >dnorm function (x, mean = 0, sd = 1, log = FALSE) .Internal(dnorm(x, mean, sd, log)) <environment: namespace:stats> How can I see the code used for densities? Thanks!

Hi there I have a data frame with about 65,000 rows and 8 variables. I am trying to get rid of the double entries of a factor variable "ID" so I can get a unique observation for each ID I tried: >dupl_unique.data.frame(data[ID,]) #I obtain a data frame with 21,547 >observations..so far so good, but then when I check for duplicates >d_duplicated(dupl2$ID)

Dear all How can I obtain the name of the argument passed in a function? Here is a simplistic example of what I would like to obtain: myfunction= function(name) { print(paste("The parameter name was",unknownFunction(name)) } myfunction(myobject) [1] "The parameter name was myobject" Thanks Francisco

Is this an interface bug? Using RGUI for windows I run into a "Not Responding" process (I "smartly" coded an infinite loop, yaiks!), I hit esc and the interpreter was stopped and I recovered the console functionality but the caption on the R icon in my windows taskbar (the individual icon shown for every software currently running in the session) was not updated so the

Hi all Is there any reason why the parameter i in a "for" loop ignores a value of zero? For example sim=c() p=.2 for(i in 0:5) {sim[i]=dbinom(i,5,p) } sim [1] 0.40960 0.20480 0.05120 0.00640 0.00032 In this example the quantile i= 0 was ignored since dbinom(0,5,p) [1] 0.32768 The same behaviour occurs if I use a while loop to perform the same calculation: sim=c() p=.2 i=0

Is there a canonical way to check if all elements of a vector or matrix are the same? Solutions below work, but look hackish to me. > x <- rep(1, 10) > all(x == x[1]) # == operator does not provide for small differences [1] TRUE > isTRUE(all.equal(x, rep(x[1], length(x)))) # ugly [1] TRUE Best, Vincent -- Vincent Goulet, Associate Professor ??cole d'actuariat

Hi everybody I want to specify the contrasts to build a cell means model on LME (each coefficient is the mean value of the independent variable for the specific category of a factor variable) when there are several factors as fixed effect in the model and also interactions between them. Can anybody give me a hint on how to do accomplish this? Also, how can I override the default

Dear all Is there a way or trick in windows to plot a line width that is not an integer i.e 1.5? I am aware that the documentation for window devices states "Line widths as controlled by par(lwd=) are in multiples of the pixel size, and multiples < 1 are silently converted to 1" but I was wondering if there is a workaround this. Also, IMHO the documentation for lwd in par may
