similar to: as.Date(Inf) displays as 'NA' but is actually 'Inf'

Hi Gabriel, The point is that it *visually* displays as NA, but is.na() still responds as FALSE. When I (and I am sure many people) see an NA, we then use is.na(). If we see Inf displayed, we then use is.infinite(). With as.Date() this breaks down. I'm not arguing that as.Date(Inf) should be coerced to NA. I'm arguing that as.Date(Inf) should be *visually* displayed as Inf (i.e. the

Richard, Well others may chime in here, but from a mathematical point of view, the concept of "infinite days from right now" is well-defined, so it maybe a "valid" date in that sense, but what day and month it will be (year will be Inf) are indeterminate/not well defined. Those are rightfully, NA, it seems? I mean you could disallow dates to take Inf at all, ever. I don't

When I read a .gz file with readLines() in 3.4.3, it returns text (and a warning). In 3.5.0, it gives a warning, but no text. Is this expected behavior or a bug? 3.4.3: > source_file = "1k_annotation.gz" > readfile_con <- gzfile(source_file, "r") > readLines(readfile_con, n = 5) [1] "#chr\tpos\tref\talt\t <truncated output here> Warning message: In

Hi, I wondered about the behavior described in the following stackoverflow question: https://stackoverflow.com/questions/20674538/mclapply-returns-null-randomly More specifically, I would like to know if you ever considered the suggestion made in the comments of the first answer, namely to somehow warn the user if one of the processes has been killed by the out-of-memory killer ? I am always

Good day, I'm trying the example cl <- makeCluster(2, type = "SOCK") from the makeCluster documentation and the R command prompt never returns. I am using a 32-bit Windows 10 computer. The problem doesn't happen on another 64-bit Windows 10 computer but does happen on another 32-bit Windows 7 computer. Can anyone reproduce it? Are there any other options that can be passed to

Dear all, I've noticed by trying to download gz files from here : https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM907811 At the bottom one can download GSM907811.CEL.gz . If I download this manually and try oligo::read.celfiles("GSM907811.CEL.gz") everything works fine. (oligo is a bioConductor package) However, if I download using download.file("

I have problem with integer overflow that I cannot understand. I have a character vector curr.lemmas with the following properties: length(curr.lemmas) # 61224 length(unique(curr.lemmas)) # 2652 That vector is the input to the following function: yules.k1 <- function(input) { m1 <- length(input); temp <- table(table(input)) m2 <- sum("*"(temp,

Hi all, I have a question with regard to making plots using function "scatterplot3d". Please see the example below. It looks like, for y axis, the tickmark text was cutoff. The number "10" does not show up completely. I tried to work with par(mpg). It does not seem to work. Hope to get some advice here. Thanks much! Hanna C <- runif(30) B <- rep(1:3, each=10) A

In the following example, the date class shows Inf as NA > as_date(Inf, origin = '1970-01-01') [1] NA This is misleading as is.na() reports incorrectly > is.na(as_date(Inf, origin = '1970-01-01')) [1] FALSE The correct approach here would probably to have an Inf (and -Inf) *displayed* rather than NA.

a) Numeric values may be either integers (signed 32 bit) or double precision (53 bit mantissa). b) Double precision constants are numeric with no decoration (e.g. 61224). Integer constants have an L (e.g. 61224L). c) 61224*61224 > 2^31-1 so that answer cannot fit into an integer. d) Exponentiation is a floating point operation so the result of 61224L^2L is a floating point answer that CAN

I stumbled across this and I am wondering if this is unexpected behavior or if I am missing something. > pnorm(-1.0e+307, log.p=TRUE) [1] -Inf > pnorm(-1.0e+308, log.p=TRUE) [1] NaN Warning message: In pnorm(q, mean, sd, lower.tail, log.p) : NaNs produced > pnorm(-1.0e+309, log.p=TRUE) [1] -Inf I don't know C and am not that skilled with R, so it would be hard for me to look into

The way cat is treating it is clearer: it

x <- as.Date(Inf, origin = "1970-01-01") x #> [1] NA str(x) #> Date[1:1], format: NA unclass(x) #> [1] Inf It's not clear what the correct behaviour is. The documentation for ?Date has: "It is intended that the date should be an integer,", which suggests that -Inf and Inf are not valid dates. But if that's true the behaviour for max.Date() needs some
