A <- "however"
alpha <- c("er","ho")
sapply(alpha, gsub, "", A)
# er ho
# "howev" "wever"
Question
I have a string for example string A="however". Now my I have a variable alpha whose value keeps changing like alpha="er","ho","er",etc.I want to remove this alpha value from the string
when the value of alpha is "er" the final value should be "however"-"er"="howev" and when the value of alpha is "ho" the final value should be "however"-"ho"="wever" and so on.How can I extract this final string.
Thanks

OTHER TIPS
Actually found its very easy
gsub(alpha,"",A)
would do it
You may use package stringr
. Function str_replace
will do the trick.
library(stringr)
A<-c("however", "evermore")
alpha <- "er"
str_replace(string=A, pattern=alpha, replacement="")
You may also substitute the substring you are removing by anything you put in replacement
