Bug in prettyNum
Thank you, Marttila and Ivan, As the original author of prettyNum() {etc ..}, I will commit such a bug fix to R-devel (and probably port it to R 4.5.0 patched) quite soon (but not yet today).

Formatting zeroes with prettyNum
You fed it two characters, "dash" and "space" and it only wanted one character so it truncated to the first character and warned you that that's what it did. If you had your space before the dash, it would have used that as your replacement character > prettyNum(0, zero.print = " - ", replace = TRUE) [1] " " Warning message: In .format.zeros(x,

Bug in prettyNum
Dear list, I'd like to report a bug in `prettyNum()`. When called with a numeric vector, the `replace.zero` argument is disregarded. > prettyNum(0, zero.print = "- ", replace.zero = TRUE) [1] "-" Warning message: In .format.zeros(x, zero.print, replace = replace.zero) : 'zero.print' is truncated to fit into formatted zeros; consider 'replace=TRUE' A

Thanks for the contribution Mikko! For testing future patches, you can actually do it right in the web browser, thanks to Heather Turner's R Dev Container, see instructions here https://contributor.r-project.org/r-dev-env/container_setup/ Best Toby On Mon, May 26, 2025 at 6:28?PM Martin Maechler <maechler at stat.math.ethz.ch> wrote: > Thank you, Marttila and Ivan, > > As

Formatting zeroes with prettyNum
Tim, The purpose of the `replace.zero` argument is to allow longer replacements. See for example the behaviour with a character vector input: > prettyNum("0", zero.print = "- ", replace.zero = TRUE) [1] "- " I'm pretty sure this is a bug, and have now posted the relevant details on r-devel. A fix would be below. Best, Mikko diff --git

Can R do zero inflated gamma regression?
Hi, Dear R-help I know there are some R package to deal with zero-inflated count data. But I am now looking for R package to deal with zero-inflated continuous data. The response variable (Y) in my dataset contains a larger mount of zero and the Non-zero response are quite right skewed. Now what i am doing is first to use a logistic regression on covariates (X) to estimate the probability of Y

Replace zeroes in vector with nearest non-zero value
Folks, If I have a vector such as the following: x <- c(0, -1, -1, -1, 0, 0, 1, -1, 1, 0) and I want to replace the zeroes by the nearest non-zero number to the left, is there a more elegant way to do this than the following loop? y <- x for (i in 2 : length(x)) { if (y[i] == 0) { y[i] <- y[i - 1] } } > y [1] 0 -1 -1 -1 -1 -1 1 -1 1 1 You can see the

[nbdkit PATCH 2/4] tests: Test retry with different fua/fast-zero flags
Add coverage for the previous patch. Although most plugins don't change can_fua or can_fast_zero on the fly, the code should still not abort when calling .zero with a flag that was permitted by the previous open but not permitted by the current open.

adding zeroes after old zeroes in a vector ??
Hello Imagine I have a vector with ones and zeroes I write it compactly: 1111111100001111111111110000000001111111111100101 I need to get a new vector replacing the "N" ones following the zeroes to new zeroes. For example for N = 3 1111111100001111111111110000000001111111111100101 becomes 1111111100000001111111110000000000001111111100000 I can do it with a for loop but I've read

3.0.1 update and compiler package
Hi, I recently updated to R 3.0.1. I'm running linux ubuntu 12.04. I realized that I have to update all the installed packages so I run > update.packages(checkBuilt=TRUE) as described here http://www.r-bloggers.com/r-3-0-0-is-released-whats-new-and-how-to-upgrade/ . The first thing it did was telling me that it will not update several packages. When it was finished I used the warnings

You're right that we may need some more infrastructure before being able to decide when to report this bit in all cases. But for raw files, that infrastructure already exists: does block_status at

ignoring zeros or converting to NA
Hi everyone, I have a matrix that has a combination of zeros and NAs. When I perform certain calculations on the matrix, the zeros generate "Inf" values. Is there a way to either convert the zeros in the matrix to NAs, or only perform the calculations if not zero (i.e. like using something similar to an !all(is.na() construct)? Thanks, rcoder -- View this message in context:

[LLVMdev] [PATCH] [ADT] APFloat - Fix sign handling for FMA results that truncate to zero.
Hi All, APFloat::fusedMultiplyAdd currently computes the wrong signed zero when small negative results are truncated back to zero in standard precision. The following snippet handles the signedness in fusedMultiplyAdd: /* If two numbers add (exactly) to zero, IEEE 754 decrees it is a positive zero unless rounding to minus infinity, except that adding two like-signed zeroes gives that

Problem about zero
Hello, everyone, There's a problem about zero in R and I really need your help. I have a vector shown as x=c(0.1819711,0.4811463,0.1935151,0.1433675), The sum of this vector is shown as 1 in R, but when I type 1-sum(x), the value is not zero, but -2.220446e-16. I can accept that this value is quite small and could be seen as zero, but there would be a problem when it's not really
