[R] Add local image as inline embedded Image

Hi All, I am using mailR package to send emails by attaching my local image files. However the image still refers to my file location and never truly embeds the image in the email. This came up in testing when my colleague was getting a red cross instead of an image. Any thoughts to resolve

Re: [R] readr to generate tibble from a character matrix

Ulrik's solution gives you factors. To get them as characters, add as.is=TRUE: > m %>% +as_tibble() %>% +lapply(type.convert, as.is=TRUE) %>% +as_tibble() # A tibble: 4 × 5 A B C D E 1 a e i 1 11.2 2 b f j 2 12.2 3 c

Re: [R] Is there a way to get R script line number

I believe the answer is: No. "Line number" is an ambiguous concept. Does it mean physical line on a display of a given width? a line of code demarcated by e.g. ; a step in the execution of script (that might display over several physical lines?) However, various IDE's have and display "line

[R] Is there a way to get R script line number

Hello, Is there a way to get the current line number in an R script? As a silly example, if I have the following script and a function called getLineNumber (suppose one exists!), then the result would be 3. 1 # This is start of script 2 3 print( getLineNumber() ) 4 5 # End of script Thanks for

Re: [R] readr to generate tibble from a character matrix

Hi, Thanks for this solution! Very slick! I see what you mean about the two calls to as_tibble(). I suppose I could do the following, but I doubt it is a gain... mm <- lapply(colnames(m), function(nm, m) type.convert(m[,nm], as.is = TRUE), m=m) names(mm) <- colnames(m) as_tibble(mm) # # A

Hi Ben, type.convert should do the trick: m %>% as_tibble() %>% lapply(type.convert) %>% as_tibble() I am not too happy about to double 'as_tibble' but it get the job done. HTH Ulrik On Thu, 6 Apr 2017 at 16:41 Ben Tupper wrote: > Hello, > > I have a workflow

This is far from portable programming but as R looks to search for /etc/localtime it is simpler for me do like that. I will not patch R source code to make "make check" step works. Then for my own code, I will use x <- as.POSIXct(strptime("2002-02-02 02:02", "%Y-%m-%d %H:%M")) or

Re: [R] as.POSIXct character string is not in a standard unambiguous format

You always need to set your timezone somehow when converting to POSIXt. Technically the method for doing this varies by OS, but on all environments I have worked with you can set the default timezone with something like Sys.setenv( TZ="Etc/GMT+5" ) In your example, some timezones supporting

[R] readr to generate tibble from a character matrix

Hello, I have a workflow yields a character matrix that I convert to a tibble. Here is a simple example. library(tibble) library(readr) m <- matrix(c(letters[1:12], 1:4, (11:14 + 0.2)), ncol = 5) colnames(m) <- LETTERS[1:5] x <- as_tibble(m) # # A tibble: 4 × 5 # A B C D

My guess is that the model has identifiability problems and that this is then causing a problem (not caught properly) in the model fitting optimizer. Is there any chance you could send data that produces the problem (off list) and I can try it out (I will only use any data for this

I have just found the solution. We have a custom Linux distribution that allows us to have several R (+ glibc and others) versions in parallel for tools related to our job domain. We have another etc/ folder for those tools and R looks for the localtime file there, not in /etc/. So linking

Re: [R] A question on modeling brain growth using GAM

If 'subjIndexF' is a factor for subject, then s(subjIndexF, bs="re") will produce a random effect for subject. i.e. each subject will be given its own random intercept term, which is a way that repeated measures data like this are often handled. The reason for the s(subjIndexF, bs="re")
