This code works perfectly in console but it doesnвЂ™t work when I try to use it in shiny. I want a specific column from the output so I use a code.

The t-test runs fine every time I run the chunk it's in, but then when I try to knit my entire notebook to a PDF, it says that there is an error in hd$maxheartrate and says '$ operator is invalid for atomic vectors.There is a function in psych package called вЂalphaвЂ™ which gives out various statistics. '$maxheartrate' is looking at the maximum heart rate for each of the patients in both samples. 'hd' and 'nohd' are subsets of the main data that observe all of the other variables but only for patients with and without heart disease respectively. In the original data set, having heart disease is noted as 1 while not having heart disease is noted as 0. 'hd' and 'nohd' are two specific subsets of a data set I imported into Rstudio about heart disease.

T.test(hd$maxheartrate,nohd$maxheartrate) I'm running into the error in the title every time I attempt to knit my notebook to a PDF. Hi, I'm very new to Rstudio and am currently using it for a summer statistics course.
