[R] Error in structure(.External(.C_dotTclObjv, objv), class = "tclObj") when selecting (HTTP mirrors) in update.packages()

Hi: When I try to run update.packages() and double click on the last option (HTTP mirrors), I receive the error message: Error in structure(.External(.C_dotTclObjv, objv), class = "tclObj") While I can reliably reproduce the error, if I double click quickly enough (decreased time between the two

Hi: When converting some code to use plot = F in a call to hist(), I received the following warning (with a much simplified example). moo<-1:10 hist(moo, las=1, plot=F) Warning message: In hist.default(moo, las = 1, plot = F) : argument '...' is not made use of >From the help page, I was able t

[R] Calling str() on mlogit object gives warnings

Hi: When I call str() on an mlogit object, I seem to get warnings. This code is from an example provided in the mlogit documentation: library(mlogit) data("Train", package="mlogit") tr<-mlogit.data(Train, shape="wide", choice="choice", varying=4:11, sep="", alt.levels=c(1,2), id="id") ml.train<-m

[R] Discrepancy in help for object.size() and question on how to round object sizes

I think there is a discrepancy In the help for object.size(). In the usage section there is the comment: ## S3 method for class 'object_size': while in the value section there is the text: An object of class ‘"object.size"’ ... And R itself says: > class(object.size(letters)) [1] "object_size

[R] Why does smoothScatter clip when xlim and ylim increased?

Hi: Is there a way to get smoothScatter to not clip when I increase the xlim and ylim parameters? Consider the following example: set.seed(17) x1<-rnorm(100) x2<-rnorm(100) smoothScatter(x1,x2) #Now if I increase xlim and ylim notice that the plot seems to be clipped at the former xlim, and ylim
