slice a string in R

string <- substr("Hello World", start = 6, stop = 11)

This code will subset and store the part of the string starting from the 6th character to the 11th character. In this case, “World” will be stored in the “string” variable.

The substr() function is used to extract a part of a string. The “start” value specifies the position of the first character to be extracted. The “stop” value indicates the position one character after the last character to be extracted. In this example, “Hello World” is the input string and the start position is 6. The stop position is defined as 11, which results in the “World” string being returned and stored in the “string” variable.
