Error: $ operator is invalid for atomic vectors

ERROR: $ OPERATOR IS INVALID FOR ATOMIC VECTORS HOW TO

'$maxheartrate' is looking at the maximum heart rate for each of the patients in both samples. 'hd' and 'nohd' are subsets of the main data that observe all of the other variables but only for patients with and without heart disease respectively. Notation for this is vect1, vect2, vect3. For example, position 1, position 2, etc. In the original data set, having heart disease is noted as 1 while not having heart disease is noted as 0. Individual elements of an atomic vector can be accessed sequentially. 'hd' and 'nohd' are two specific subsets of a data set I imported into Rstudio about heart disease. Im attempting to generate a report of which data are missing from a Redcap project. If your question has been answered, don't forget to mark the solution How do I mark a solution Find the reply you want to mark as the solution and look for the row of small gray icons at the bottom of that reply. T.test(hd$maxheartrate,nohd$maxheartrate) Error: operator is invalid for atomic vectors 114. I'm running into the error in the title every time I attempt to knit my notebook to a PDF. Is.recursive(data) # Apply is.Hi, I'm very new to Rstudio and am currently using it for a summer statistics course. Is.atomic(data) # Apply is.atomic function to data It allows only a literal character string or a symbol as the index. The form using applies to recursive objects such as lists and pairlists. You are treating x like a dataframe but it is a vector. In R language, you get the error, operator is invalid for atomic vectors when you try to apply to a non-recursive object. Is.recursive(vec) # Apply is.recursive function to vector You cannot use the operator to extract from an atomic vector (it does not make sense, there are no variables to extract from a vector). Is.atomic(vec) # Apply is.atomic function to vector
