To get the substring between two specific characters in R, you can use the `substr` function with the positions of the characters.
In this example,
url
with a value of "https://example.com/page?query=1"
.substr
function with the positions of '/'
and '?'
to get the substring between the characters.url <- 'https://example.com/page?query=1'
start <- which(strsplit(url, '')[[1]] == '/') + 1
end <- which(strsplit(url, '')[[1]] == '?') - 1
substring <- substr(url, start, end)
print(paste('Substring between '/' and '?':', substring))
Substring between '/' and '?': page
In this example,
str
with a value of "Hello,World!"
.substr
function with the positions of ','
and '!'
to get the substring between the characters.str <- 'Hello,World!'
start <- which(strsplit(str, '')[[1]] == ',') + 1
end <- which(strsplit(str, '')[[1]] == '!') - 1
substring <- substr(str, start, end)
print(paste('Substring between ',' and '!':', substring))
Substring between ',' and '!': World
