Letting a user supply the autoprint function would be nice also. In a way you can already do that, using addTaskCallback(), but that doesn't let you suppress the standard autoprinting. Having the default autoprinting do its own style of method dispatch doesn't seem right. Bill Dunlap TIBCO Software wdunlap tibco.com On T...

In R-3.6.0 autoprinting was changed so that print methods for the storage modes are not called when there is no explicit class attribute. E.g., % R-3.6.0 --vanilla --quiet > print.function <- function(x, ...) { cat("Function with argument list "); cat(sep="\n ", head(deparse(args(x)), -1...

However it also seems that print calls in packages should be independent of user customisations. For instance a package author might gather tabular data in a matrix or data frame and print() it as part of a larger print method. In that case, user customis...

...to customise auto-printing for base types and even classed objects as that'd be useful for both users and IDEs. However S3 dispatch may not be optimal for this because it essentially requires polluting the global environment with print methods. Maybe it'd make sense to add getOption("autoprint") which should be set to a user- or environment- supplied function. That function would do the dispatch. I'd be happy to send a patch for this, if it makes sense. Best, Lionel > On 21 May 2019, at 13:38, William Dunlap via R-devel <r-devel at r-project.org> wrote: > > It...

Hi, All: I'm having trouble getting deparse(substitute(x)) inside print.generic to consistently I'm having trouble getting a print.something to work consistently. Consider the following toy example: # Define an object of class 'dum' k <- 1 class(k) <- 'dum' str(k) # as expected # Define print.dum print.dum <- function(x, ...)

Because it doesn't work that way... First of all, your print.dum relies on autoprinting of its return value, it doesn't print anything itself. That's not how one usually writes print methods: You should print something and (usually) return the argument invisibly. Autoprinting calls the print method to do the actual printing and returns the object invisibly, irrespective o...

Could anyone please explain to me why the following writes nothing into "all.Rout" file? If the "for" loop is removed, t.test output can be written into "all.out". Thanks in advance. Minghua Yao ...... zz <- file("all.Rout", open="wt") sink(zz) for(i in 1:n) { Cy3<-X[,2*i-1]; Cy5<-X[,2*i]; t.test(Cy3, Cy5)

I don't understand why I get the following results. I define two classes 'Base' and 'Derived', the latter of which 'contains' the first. I then define a generic method 'test' and overload it for each of these classes. I call 'callNextMethod()' in the overload for Derived. From the output, it appears that the overload for Base gets called twice. Why is

Hi, I tried to run the following script with R 2.4.0. The data stuff is commented out because data are already in memory. #db <- read.csv("normais.csv", sep=";", quote="", header=T) sink("normais-chi.txt", append=T, type = "output", split=T) #sink("normais-chi.txt", append=T) table(db$agua, db$mBerg) chisq.test(db$agua, db$mBerg,

If I copy the following commands in my batch file to the R console, R creates a file named "basicStatsIBM.lis" with the program output in it: Sortie <- file(description = "basicStatsIBM.lis", open = "wt", blocking = TRUE, encoding = "UTF-8") sink(file = Sortie, append = FALSE, type = "output", split = FALSE) basicStats(ibm) close(Sortie)

Hi, If I type it in the command line I get, as expected: > 1:30 [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 [26] 26 27 28 29 30 > q() Save workspace image?
