Hello, for reasons I want to know the return value of TYPEOF(R_NilValue), I expect it to be NILSXP, but I can't find this documented anywhere. Ideally, I'd like to see the source definition of R_NilValue, but after fair bit of searching I cannot find an obviously location for this. Would someone please point me in the right direction? thanks -- CRICOS provider code 00123M

...n of these (how many, I can't see since due to the density of the labels). My question is how I can get a sane number of labels along the x axis (about 5-10 would be good). I suspect that 'scales' might be the way to go, but I can't see an obvious option to do this. thanks -- Dan Kortschak <dan.kortschak at adelaide.edu.au>

...e represented as a fully allocated SEXP value rather than just a C NULL. Also, whether C NULL is used to any great extent within the internal code. Note that the Go API provides a mechanism to easily reconvert the nil's used back to a R_NilValue when returning from a Go function[3]. thanks Dan Kortschak [1]https://github.com/rgonomic/rgo [2]https://github.com/rgonomic/rgo/issues/1 [3]https://pkg.go.dev/github.com/rgonomic/rgo/sexp?tab=doc#Value.Export

Hello, I have a set of data frames, generated by an SQL query that I am working with. Because of the way the query was written, zero values for the dependent variable (V2 in the example) are not recorded. Up until now this has not been a problem. I would like to be able to fill all absent data with 0. Current state of data (e.g.): >

Hello R users, I have a data set which is a set of lengths and types of objects. I want to calculate the mean length for each type of object as opposed to the mean of all the objects in the set. This is in order to make a comparison between the lengths of each type of objects and the number of those objects. > x Chromosome Begin End Type Class Norm Length 458327

Hi R users, I have a very large data set that has two conditioning variables for the test I want to perform. A toy set can be simulated: type<-sample(1:3,100,replace=TRUE) class<-sample(1:20,100,replace=TRUE) value<-rnorm(100) data<-cbind(type,class,value) (though type and class are alphanum) I want to perform the three pair-wise t-tests between types for each class in data. Can

..." in some cases to avoid confusion, e.g. for values types as "void *". SEXPs that packages obtain using the interface in WRE should not be C NULL, only R NULL (R_NilValue). External pointers can become C NULL and this is documented in WRE 5.13.

Hi, This is another question relating to my 2 factor figure. densityplot(~End-Begin | Type * Chromosome, data=Mon, layout=c(5,12), xlab="Element Length",type="percent", col="grey60", strip=strip.custom(style=3, bg="grey90", par.strip.text=list(cex=0.5))) I would like to flip the plot so those at the bottom are at the top and so on. I have tried using a

Hi, I'm making a multipanel lattice densityplot figure with 2 factors (3 and 20 classes in each factor) with the following statement (the type="percent" is there to prevent plotting the actual points which detract from the figure - is there another way of doing this?): densityplot(~End-Begin | Type * Chromosome, data=Mon, layout=c(5,12), xlab="Element

Hello, I'm from Espressif Systems company, software department. Our company develops processors based on Xtensa architecture like ESP32 and ESP8266. We propose the integration of a backend targeting Xtensa architecture. We started to develop LLVM Xtensa backend almost a year ago. The reason was that we saw a demand from our large developers community. Currently only GNU compiler supports

Hello, I am plotting a set of data where subsets are of different length and not all sites are noted in the data sets. To indicate the extent of sites, I am marking this with a line on the xyplot being produced: require(lattice) lengths<-as.integer(runif(10)*100) results <- matrix(ncol=3) for (i in 1:10) { gap <- 1-runif(1)/10 pos <- 1:as.integer(lengths[i]*gap) seq <-

Hi, Am am plotting aggregated frequency data (extracted from an RDBMS) relating to DNA sequence features for each of the human chromosomes as described in the table chromosomes below (the frequency data is in a table 'hits' that has a value (or not) for each of a set of bins across each chromosome). I would like to mark the extent of the chromosome (according to the length value in
