Trying new RFc package to get climate data into R from FetchClimate service.

See all the available climate variables here.

library(knitr)
opts_knit$set(upload.fun = imgur_upload)

library("RFc")
library("raster")
library("rworldmap")
data("coastsCoarse")

Fetching gridded data

Fetching temperature for Europe for Januaries 2000-2010 with 0.5 degrees resolution

pet <- fcGrid(variable = "airt",
              latitudeFrom = 35, latitudeTo = 60,latitudeBy = 0.5,
              longitudeFrom = -10, longitudeTo = 30, longitudeBy = 0.5,
              firstDay = 1,lastDay = 31,
              firstYear = 2000, lastYear = 2010)

Hi there!

I get an error when executing the example code:

install.packages("RFc")

library(RFc)

hour.ts <- fcTimeSeriesHourly(variable="airt",
latitude = 37.4, longitude = -6,
firstYear = 1978, lastYear = 1978,
firstDay = 1, lastDay = 1,
startHour = 0, stopHour = 24)

Error in x[sapply(x, is.null)] <- NA : invalid subscript type 'list'
