Try this:
> gsub("-(\\w)", "\\L\\1", test, perl = TRUE)
[1] "Kwak Minjung"
or this:
> library(gsubfn)
> gsubfn("-(\\w)", tolower, test)
[1] "Kwak Minjung"
Question
I have a bunch of strings with a hyphen in it. I want to remove the hyphen and convert the following letter to lower case while keeping all the other letters intact. How do you accomplish task in R?
test <- "Kwak Min-Jung"
gsub(x=test,pattern="-(\\w)",replacement="\\1")
# [1] "Kwak MinJung" , Not what I want
# I want it to convert to "Kwak Minjung"
La solution
Try this:
> gsub("-(\\w)", "\\L\\1", test, perl = TRUE)
[1] "Kwak Minjung"
or this:
> library(gsubfn)
> gsubfn("-(\\w)", tolower, test)
[1] "Kwak Minjung"
Autres conseils
Use \\L
or \\U
to change the case in the replacement argument. You can use \\E
to end the effect of the case conversion.
gsub(x=test,pattern="-(\\w)",replacement="\\L\\1", perl=TRUE)
# [1] "Kwak Minjung"
