Remove parentheses and text within from strings in R

by

A gsub should work here

gsub("\\s*\\([^\\)]+\\)","",as.character(companies$Name))
# or using "raw" strings as of R 4.0
gsub(r"{\s*\([^\)]+\)}","",as.character(companies$Name))

# [1] "Company A Inc"  "Company B"      "Company C Inc."
# [4] "Company D Inc." "Company E"

Here we just replace occurrences of “(…)” with nothing (also removing any leading space). R makes it look worse than it is with all the escaping we have to do for the parenthesis since they are special characters in regular expressions.
