While using the Boot function from the car package I get the error message
Error in get(".y.boot", envir = .carEnv) : object '.carEnv' not found
I suspect I have inadvertently changed/set something in my OS and have no idea what it might be. Running the code below returns an error on my desktop but runs without error on a laptop running the same OS (Yosemite) as well as a desktop running Windows 7 (all using R-3.1.2). The code that triggers the message is
library(car)
swiss.lm <- lm(Fertility ~ Education, data = swiss)
BC <- Boot(swiss.lm, R = 999, method = "case") # No Problems
BR <- Boot(swiss.lm, R = 999, method = "residual") # Problems now
Error in get(".y.boot", envir = .carEnv) : object '.carEnv' not found
I have reinstalled R but the error still appears when running the above code. Any suggestions as to what I have done and how to get the code to run and find the environment would be most appreciated. TIA!
