Re: [R] troubles with foreign:read.dbf

[Patrick Giraudoux]

Ashes of my head and all those sorts of things...
If I was a totally a newbie in R, I could claim for some sort of excuse, 
but it is definitely not the case, even.
Thanks !
Patrick

Re: [R] troubles with foreign:read.dbf

You seem to have a typo.
In the case that works your filename is "Mailles_2011a.dbf"
but in the case that fails your filename is "Mailles_2011a.shp"
(different extensions)

HTH,
Eric

[R] troubles with foreign:read.dbf

[Patrick Giraudoux]

Dear listers,

I am using the package foreign function read.dbf and meet the following 
issue:

i<-"Mailles_2011a.dbf"

dbf<-read.dbf(i)

works well BUT

if I have a vector such as

files <- c("Mailles_2011a.shp", "Mailles_2011p.shp", 
"Mailles_2012a.shp", "Mailles_2012p.shp", "Mailles_2013a.shp", 
"Mailles_2013p.shp", "Mailles_2014p.shp", "Mailles_2015a.shp", 
"Mailles_2015p.shp", "Mailles_2016p.shp")

for(i in files) {
dbf<-read.dbf(i)
names(dbf)
}

gives the following error message:

Error in read.dbf(i) : unable to open DBF file

Same error with e.g.

dbf<-read.dbf(files[1])

Any idea about what's happening?

Patrick
