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.
