The packages "readxl" and "haven" (and possibly others) no longer access files
on shared network drives. The problem appears to be in the normalizePath()
function. The file can be read from a local drive or by functions that don't
call normalizePath(). The error thrown is
Error: path[1]="\\Hzndhhsvf2/data/OCPH/EPI/BHSDM/Group/17.xls": The system
cannot find the file specified
Here's my session:
library(readxl)
library(XLConnect)
# attempting to read file from network drive
df1 <- read_excel("//Hzndhhsvf2/data/OCPH/EPI/BHSDM/Group/17.xls")
# pathname is fully qualified, but error thrown as above
cat(normalizePath("//Hzndhhsvf2/data/OCPH/EPI/BHSDM/Group/17.xls"))
# throws same error
# reading same file with different function
df2 <- readWorksheetFromFile("//Hzndhhsvf2/data/OCPH/EPI/BHSDM/Group/17.xls", 1)
# completes successfully
# reading same file from local drive
df3 <- read_excel("C:/17.xls")
# completes successfully
