I am trying to keep only the records which contain a particular promotion name from a list of promotion names in R.
top_10_promo_name <- c("Price Winners", "Two Day Sale", "Weekend Markdown", "Go For It", "Save-It Sale", "One Day Sale", "Shelf Clearing Days", "Big Time Discounts", "Super Duper Savers", "Two for One") sales_promo_10 <- sales_promo[as.character(sales_promo$promotion_name) %in% top_10_promo_name,]
However,even though there is no error all the promotion names are getting selected.
I know this is a very basic question but I am not being able to figure it out.Can someone please help me with this??
