Hi R-User
I was trying to make a raster map with WGS84 projection
in R, but I could not make it. I found one data set in Google that data
is almost the same format as of mine. I wanted to make a raster map of
temperature with 1 degree spatial resolution for the global scale.
I
could make it in the GIS software but I do have many variables (to be
many raster images) and ultimately I am importing them into R for
further analysis. Therefore, I wanted to make them in R, if possible.
But, I am wondering how I can create a raster map in R.
(I have provided link of data for your references, this is an example of data
set).
I am really appropriating for your help.
#--------------------------------------------------
I downloaded the following packages
#create a raster map from scratch
install.packages("raster", dependencies=TRUE)
library(raster) # raster data
install.packages("rgdal", dependencies=TRUE)
library(rgdal) # input/output, projections
install.packages("rgeos", dependencies=TRUE)
library(rgeos) # geometry ops
install.packages("spdep", dependencies=TRUE)
library(spdep) # spatial dependence
install.packages("pastecs", dependencies=TRUE)
library(pastecs)
pts<-read.table.url("https://www.betydb.org//miscanthusyield.csv";, header=T,
sep=",")
proj4string(pts)=<- CRS("+proj=longlat +datum=WGS84")
after that, what I am supposed to do for creating a raster map? any suggestions?
