Hi R Users,
I commonly import multiple .csv files and then write loops to work with
those files like this:
>setwd('C://Nathaniel/R/allfiles')
>files<-list.files()
>allfiles<-lapply(t1,read.csv)
>for (i in 1:47) {
> t1<-allfiles[[i]]
etc. etc.
I have written a script that I would like to loop to work with a folder of
400+ .shp files. Is there an equivalent way to read in all the shapefiles
so that I can run a loop?
I tried this:
>setwd('C://Nathaniel/R/shapefiles')
>t1<-list.files()
>t2<-lapply(t1,readShapePoly)
which returned this error:
"Error in Fun(c("shape1.dbf", "shape1.prj",
"shape1.sbn", "shape1.sbx", :
missing layer"
and I tried this:
>setwd('C://Nathaniel/R/shapefiles')
>t1<-list.files()
>t2<-lapply(t1,readOGR)
which returned this error:
"Error in getinfo.shape(filen) : Error opening SHP file"
I've searched the archives and wasn't able to find anything like this.
My
understanding of R code is rudimentary, so any help would be greatly
appreciated. Thanks for considering my problem.
Best regards,
Nathaniel
