>From the following lines of code on an iMac running Catalina 10.15.7
library(readxl) fname <- "/Volumes/SD/LabData/Lorentz/Lorentz.xlsx" Helm <- read_excel(fname,sheet="Helmholtz") I get the following annoying error: Error: Evaluation error: zip file To me this makes no sense: the file in question is not a zip file. The excel file in question, however, is either open on excel, or recently opened in excel. Does anyone know about this error, and what to do about it? I am running R version 3.5.1 Thanks for any assistance you can provide.
