To rename values in R that need to be truncated at various positions, you can use the substring()
function.
Syntax:
substring(x, first, last)
x
is the vector or column that you want to modify.first
is the position of the first character to include in the new name.last
is the position of the last character to include in the new name.Example:
Consider a data frame with a column named Name
that has values you want to truncate, like below:
df <- data.frame(Name = c("John Smith", "Jane Doe", "William Johnson", "Emma Stone"))
To keep only the first 5 characters of each name, you can use the substring()
function like this:
df$Name <- substring(df$Name, 1, 5)
This will modify the Name
column to have the new truncated names:
> df
Name
1 John
2 Jane
3 Willi
4 Emma
