Hi, huge fan of your videos. I have researched for days with no result, so I am desperately reaching out. In excel, you can write a conditional statement "if (condition) then (true value), (false value). In excel, those true/false values can reference the value of another column.

Example: If c"animal" = zebra, then reference corresponding value in column "zebra stripes", if not then blank.

How do you do this in R? It wont seem to let me reference the corresponding value of another column as the "true" or "false" output results of a conditional

Hi! what happens when this appears in RMarkdown, I'm creating a barplot and it does work in a normal script but when I put it on the RMarkdown I have this: "Object of Type Closure is not Subsettable"

Joachim: What a resource you are! I am so happy to have found your site. I am taking a MOOC Coursera class and have been stymied with this error. Your explanation of the cause has been very eyeopening, but I am still unable to overcome the error. Here is the code I am entering. It seems R is "seeing" brackets even though I am entering parentheses. Please help and thank you in advance.
