Hello! I'm very new to using R and I'm trying to create a new variable that is the natural log of the number of patients (which is a column of data in my data set) +1 so that I can get -Inf if there are 0 number of patients when logged.
I've been trying to figure this out for a while and I can't seem to get anywhere, any help would be greatly appreciated. Thank you!
If I've understood correctly, you have a data frame that might have a column of patients that looks like this:
df <- data.frame(patients = sample(0:2, 10, replace = T))
df
# in base R, you can just create a new variable column like so:
df$log_of_patients_plus_one <- log(df$patients)+1
If that's not what you're looking for, you might need to give a more detailed example, as well as what output you're looking for.
Thank you very much!
Here is a paper titled "Do not log transform count data."
