'region' not found for subset

kmaslowski

My student types in what the video walkthrough shows and what other students have done successfully (Shown below)

subset(my_*dat, region == "Midwest" & default_*rate > 33)

He gets in response

Error in eval(e, x, parent.frame ()) : object 'region' not found

Traceback:
subset(my*dat, region == "Midwest" & default_*rate >33)
subset.data.frame(my_dat, region== "Midwest" & default_rate> 33)
eval(e, x, parent.frame())
eval(e, x, parent.frame())

(code formatting fixed by @dylarm )

kmaslowski Checking in, did those questions help fix your problem? Or is it something else?

A couple of questions to help troubleshoot:

Is this the exact thing they typed in? (as in, this is copy&pasted over, not retyped)
Have all of the previous cells been run before attempting this one?

My hunch is that the comma between my_dat and region was missed, but we'll see.

Edit: @kmaslowski after fixing the code, it seems that my_datwas not what was actually typed, but an asterisk was also put in (accidentally?). Could also just be from the formatting in this forum. For the future, if you include code (because underscores are also considered italics), use three ` in a row to type code.

Hi - I have a student trying to use the select command in 1.3 and it is returning the error that variable "name" is not a valid header. We have tried typing it exactly and copying from the example, both times getting the same error.

bsmith4sj Provided some questions and info in your thread, since it does appear that you're using a different function (and so the error source might be different). 🙂
