In R I want to do a like in an if statement like the example below where I'm searching for any colors in the mix$color column that contain the word red and setting a new variable in the mix dataframe to the color red.
mix$newcolor <- if(grep("Red",mix$color) "red"
And here's some sample data for the dataframe mix:
AliceBlue BlueViolet DarkRed MediumVioletRed
I'm getting this error message:
Warning message: In if (grepl("deep red", mix$color) == TRUE) "red" : the condition has length > 1 and only the first element will be used
I think that grepl should be returning a TRUE or FALSE boolean value so that should be acceptable but I'm missing something (or a lot).
Thanks for your help.
you can use grepl and an ifelse statement:
> color = c("AliceBlue", "BlueViolet", "DarkRed", "MediumVioletRed")
> ifelse(grepl("Red",color),"red","other")
[1] "other" "other" "red" "red"
