Evan, there are oodles of ways to do many things in R, and mcu of what the
tidyverse supplies can often be done as easily, or easier, outside it.
Before presenting a solution, I need to make sure I am answering the same
question or problem you intend.
Here is the string you have as an example:
Here's a function that can get the interval sizes for you.
getStringSegmentLengths <- function(s, delim, ...) {
nchar(unlist(strsplit(s, delim, ...))) + 1L
}
It uses strsplit to return a list of all the segments of the string
separated by delim. delim can be a regular expression and with
You could split the string into letters and figure out which ones are �b�
which(strsplit(x, "")[[1]] == "b")
and then find the difference between each position, �anchoring� at position 0
> diff(c(0, which(strsplit(x, "")[[1]] == "b")))
[1] 2 4 1 6 4
From: R-help on behalf of Evan Cooch
try
gregexpr('b+', target_string)
which looks for one or more b characters, then get the attribute
"match.length"

Was wondering if there is an 'efficient/elegant' way to do the following
(without tidyverse). Take a string
abaaabbabaaab
Its easy enough to count the number of times the character 'b' shows up
in the string, but...what I'm looking for is outputing the 'intervals'
between occurrences of

Strange! But it's been fixed in Org, so whatever caused

Ok, it's not ob-R. If I load ob-R I still get
#+begin_src R :results output :session *R* :exports both
x <- 2:4
print(x)
#+end_src
#+Results[5cafbcfc3677a0d07c696e39397c23e61ba0c021]:
