问题 library(utils) a<-zip.file.extract("\\1\\1.csv",zipname="drivers.zip") Error: could not find function "zip.file.extract" What's going on? 回答1: zip.file.extract() is a defunct function as of R 2.14 (see ?"utils-defunct" help page or try brining up the ?zip.file.extract help page). Use the unzip() function instead. Perhaps unzip("drivers.zip", files="\1\1.csv") or you can omit the files= to extract all files in the zip archive to the current working directory. 来源： https://stackoverflow.com
