sorry for the easy questions but I have this problem. I had read Help but I
didn't find this question. Sorry for desturbing but I am a brand new in R,
sorry again
# I have a shape file with 4 column (soil, ID, country, pH)
sample <- readOGR(".", "sample")
summary("sample")
# I wish select only the ID (2 column) and pH (4 column)
# in help I found this sw[1:3] for select the 1°,2°,3° columns, but I wish
to select only the
# 2° and 4°
sample_real <- sample[?????]
writeOGR(sample_real, ".", "sample_real", driver="ESRI Shapefile")
thanks and sorry again for the question and for your time
Gianni
