...nt to know is this behavior expected and why is that ?

typeof applied to a factor always seems to return "integer", independently of the type of the levels. This has a strange side effect. When a variable is "imported" into a data frame, its type changes. character variables automatically are converted to factors when imported into data fr...

S Programming by Venables and Ripley (2000) says on page 8, "R objects have another way to give information using the function \tttext{typeof}, which often gives the same information as \tttext{storage.mode}." It implies that there are some differences between typeof and storage.mode. However, according to ?typeof and ?storage.mode, it doesn't seem to be so. Could somebody let me know if there is any difference? If there is, wh...

Hello Everyone, I am using R 2.15.0 and I came across this behaviour and I was wondering why I don't get an integer vector or and integer matrix with the following code: > z <- c(1, 2:0, 3, 4:8) > typeof(z) [1] "double" > z <- rbind(1, 2:0, 3, 4:8) Warning message: In rbind(1, 2:0, 3, 4:8) : number of columns of result is not a multiple of vector length (arg 2) > typeof(z) [1] "double" > z <- matrix(c(1, 2:0, 3, 4:8), nrow = 5) > typeof(z) [1] &quot...

Hello, Doing typeof() on an object appears to reset the "named" field in its sxpinfo header to 2, which can change the way that subsequent subassignment operations are carried out: X <- 1:5e7 .Internal(inspect(X)) # @4eeb0008 13 INTSXP g0c7 [NAM(1)] (len=50000000, tl=0) 1,2,3,4,5,... system.time(X[1] &l...

Does anyone know why a data frame created with empty character columns converts them to integer columns? > df<-data.frame(a=character(0),b=character(0)) > df<-rbind(df,c("a","a")) > typeof(df[1,1]) [1] "integer" AsIs doesn't help: > df<-data.frame(a=I(character(0)),b=I(character(0))) > df<-rbind(df,I(c("a","a"))) > typeof(df[1,1]) [1] "integer" Any suggestions on how to overcome this would be appreciated.

Hi, The problem arises when I lazyLoad() the .Random.seed from a previously saved database. To simplify the process of reproducing the problem, see the example below: ## this assignment may not really make sense, but illustrates the problem delayedAssign('.Random.seed', 1L) typeof(.Random.seed) # [1] "integer" rnorm(1) # Error in rnorm(1) : # .Random.seed is not an integer vector but of type 'promise' typeof(.Random.seed) # [1] "integer" So there must be an "attribute" "promise" somewhere attached to .Random.seed, and I can...

I'm observing that base::sum(x, na.rm=FALSE) for typeof(x) == "double" is much more time consuming when there are missing values versus when there are not. I'm observing this on both Window and Linux, but it's quite surprising to me. Currently, my main suspect is settings in on how R was built. The second suspect is my brain. I hop...

Dear list members, I recall seeing a convenience function for applying multiple functions to one object (i.e., almost the opposite of 'mapply?) somewhere. Example: If the function was named ?fun? the output of fun(3.14, mode, typeof, class) would be identical to the output of c(mode(3.14), typeof(3.14), class(3.14)) Is my memory failing me, or does such a function already exists in a package? Of course, it?s not difficult to define a summary function and apply this to the object, but writing, for example, fun(x, mean,...
