Hi there, I'm sorry for the bad subject decision. Couldn't describe it better...
In my dataset called "dataSet" I want to create a new variable column called "deal_category" which depends on another column called "trans_value". In column "trans_value" I have values in USDm. Now what I want to do is to give these values a category called "low", "medium" or "high". The classification depends on the size of the values. "low", if value in "trans_value" is < 200 USDm "medium", if value x in "trans_value" is: 200 USDm =< x < 500 USDm "high", if value in "trans_value" is: >= 500 USDm Having defined these deals with low, medium, high I want to run a lm() with these categories as independent variable. deal_category2 <- factor(deal_category) levels(deal_category2) <- c("low", "medium", "high") reg_1 <- lm(dep_var1 ~ indep_1 + indep_2 + deal_category2) summary(reg_1) Is this correct? Does R recognize my categories as variables? Thanks for all your support!
