How to use the strsplit function with a period

Question

I'd like to separate the following string into two parts based on the periods.

I tried strsplit() with the split argument set to "." but didn't obtain the desired result.

 

"I.want.to.split" is s - "I.want.to.split" is s - "I.want.to

 

splitstretch (s, ".")

I want s to be separated into four components in a list, as shown below.

 

"I" "want" "to" "split" "I" "want" "to" "split" "I" "want" "to" "spli

 

So, what should I do now?

Answer 1

Since the dot has a specific meaning in regex that means "match any single character (excluding newline)," you must either put it inside a character class or come before it with two backslashes to escape it.

"I.want.to.split," says s.

s, '.' in strsplit(s)

# [[1]]

I want to split up, number one.
