How to Convert “space” into “%20” with R

问题

Referring the title, I'm figuring how to convert space between words to be %20 .

For example,

> y <- "I Love You"

How to make y = I%20Love%20You

> y
[1] "I%20Love%20You"

Thanks a lot.

回答1:

gsub() is one option:

R> gsub(pattern = " ", replacement = "%20", x = y)
[1] "I%20Love%20You"

回答2:

Another option would be URLencode():

y <- "I love you"
URLencode(y)
[1] "I%20love%20you"

The function curlEscape() from the package RCurl gets the job done.

library('RCurl')
y <- "I love you"
curlEscape(urls=y)
[1] "I%20love%20you"
