Dear all. Is there a way to download global elevation data at the 1? x 1? resolution in R using a given set of coordinates? I know about the getData() function but can many coordinates be passed through this? Thanks...

Dear all, Please forgive my inexperience with spatial downscaling. I am interested in spatial downscaling of global temperature to grid cell. Is there a package in R that can perform this function? Any help/guidance will be highly appreciated. Sincerely...

Dear all, I have a set of coordinates. Is it possible to extract climate data (temperature and precipitation) by coordinates using the R packages such as rnoaa? For example; out <- ncdc(datasetid='ANNUAL', stationid='GHCND:USW00014895', datatypeid='TEMP') But instead...

Dear all, I am using the country-level shapefile from GADM. I would like to merge Cyprus and North Cyprus into one polygon. Is this possible? I am using rgdal to read the shapefile, subset, and then rewrite it. Any...

Greetings everyone, I have a question on extracting country-level data from CRU ( https://crudata.uea.ac.uk/cru/data/hrg/cru_ts_4.06/crucy.2205251923.v4.06/countries/tmp/). The data for each variable are available for individual...

Greetings, i am trying to export a shapefile using the following command; st_write(weight.sf, "weight.shp, driver="ESRI Shapefile") But getting the following warning; 1: In abbreviate_shapefile_names(obj) : Field names abbreviated for ESRI Shapefile driver The...

I have weekly panel data for more than a hundred cities. The independent variables are temperature and precipitation. The time dimensions are year and week and likely have time invariant characteristics and are all important for proper estimation. Could I...

Dear all. Is it possible to convert.identify iso3 country names to the seven continent names? # Asia, Africa, Antarctica, Australia, Europe, South America, and North America, I have tried the following: ### region <- merge(countryExData,df,by.x='ISO3V10',by.y...

Dear John, Apologies for not providing reproducible example. I just tried with a plm example but ran into the same issue; library(plm) data("Produc", package = "plm") zz <- plm(log(gsp) ~ log(pcap) + log(pc) + log(emp) + unemp, data = Produc...

Dear all, I apologize as this may not be a strictly R question. I am running GAM models using the mgcv package. I was wondering if the interpretation of the smooth splines of the 'x' variable is the same in...

Dear all, I am struggling to convert a dataframe with 49 years of data for 259,200 coordinates. How can I convert this dataset into a NetCDF file with the following attributes; class : RasterBrick dimensions : 360, 720, 259200, 10 (nrow...

I have a SpatialPointsDataFrame with the following attributes. Is it possible to convert this to a SpatialPolygons or SpatialPolygonsDataFrame? Thank you! Sincerely, Milu class : SpatialPointsDataFrame features : 21441 extent : -179.5, 179.5, -89.5, 83.5 (xmin, xmax, ymin, ymax...

Dear all, I am running the following panel regression; plm1 <- plm(formula = log(y) ~ x1 + I(x1^2) + heat*debt_dummy + tt, data = df, index=c("region","year")) where 'df' is a pdata.frame. I would like to obtain marginal...

I have a dataframe (more than 50,000 observations), of cities in the EU. My goal is to assign NUTS-2 code to each of these cities. However, I am not aware of any direct way of achieving this, so...

Is it possible to convert latitude and longitude into addresses in R using Wikimapia mapping instead of Google? The reason being that Wikimapia addresses have more details. This is the code I have been using but this obtains the information...
