The 2015 does contain three files. ________________________________ From: jing hua zhao <jinghuaz...@hotmail.com> Sent: 10 February 2017 00:13 To: r-devel@r-project.org Subject: issue with unz()?
Dear R-devel, url0514 <- "http://data.dft.gov.uk.s3.amazonaws.com/road-accidents-safety-data/Stats19_Data_2005-2014.zip"; file0514 <- c("Vehicles0514.csv","Casualties0514.csv","Accidents0514.csv") temp <- tempfile() download.file(url0514,temp) a0514 <<- read.csv(unz(temp, file0514[3])) c0514 <<- read.csv(unz(temp, file0514[2])) v0514 <<- read.csv(unz(temp, file0514[1])) cts [a|c|v]0514, but this is not the case if zip file contains only one file, i.e., file2015 <- c("Vehicles_2015.csv","Casualties_2015.csv","Accidents_2015.csv") url2015 <- "http://data.dft.gov.uk/road-accidents-safety-data/RoadSafetyData_2015.zip"; download.file(url2015,temp) v2015 <<- read.csv(unz(temp, file2015[1])) c2015 <<- read.csv(unz(temp, file2015[2])) a2015 <<- read.csv(unz(temp, file2015[3])) so to combine [a|c|v]0514 and [a|c|v]2015, I need to add something like names(a0514)[names(a0514)=="�..Accident_Index"] <- "Accident_Index" names(c0514)[names(c0514)=="�..Accident_Index"] <- "Accident_Index" names(v0514)[names(v0514)=="�..Accident_Index"] <- "Accident_Index" This is unnecessary under Linux (RHEL), since those i..Accident_Index have no i.. prefix. Do I miss anything here? Many thanks, Jing Hua Zhao [[alternative HTML version deleted]]
