everybody, sorry for disturb, but I am being quite new with r faced a crucial difficuty:
I want to create an animated map of Russin with changes in unemployment with differnt years, like. On the image you can see data for one year
require(sp)
require(maptools)
require(RColorBrewer)
require(rgdal)
rus<-url("http://www.filefactory.com/file/4h1hb5c1cw7r/n/RUS_adm1_RData")
print(load(rus))
unempl <- read.delim2(file="C:\\unempl1.txt", header = TRUE,
sep = ";",quote = "", dec=",", stringsAsFactors=F)
gadm_names <-gadm$NAME_1
total <- length(gadm_names)
pb <- txtProgressBar(min = 0, max = total, style = 3)
order <- vector()
for (i in 1:total){
order[i] <- agrep(gadm_names[i], unempl$region,
max.distance = 0.2)[1]
setTxtProgressBar(pb, i) # update progress bar
}
col_no <- as.factor(as.numeric(cut(unempl$data[order],
c(0,2.5,5,7.5,10,15,100))))
levels(col_no) <- c("<2,5%", "2,5-5%", "5-7,5%",
"7,5-10%", "10-15%", ">15%")
gadm$col_no <- col_no
myPalette<-brewer.pal(6,"Purples")
proj4.str <- CRS("+init=epsg:3413 +lon_0=105")
gadm.prj <- spTransform(gadm, proj4.str)
spplot(gadm.prj, "col_no", col=grey(.9), col.regions=myPalette,
main="Unemployment in Russia by region")
The result, which I willing to get is something like animation here: http://spatial.ly/2011/02/mapping-londons-population-change-2011-2030/ However, I googled a lot, read a number of themes in http://stackoverflow.com including the following: Creating a Movie from a Series of Plots in R, but couldn't do the right thing still.
thank you in advance!
I've comed up with something like this, can anyone please tell me where is the mistake:
require(animation)
require(sp)
require(RColorBrewer)
require(classInt)

max.distance = 0.2)[1]
setTxtProgressBar(pb, i) # update progress bar
}

setTxtProgressBar(pb, i) # update progress bar
}
col_no_1 <- as.factor(as.numeric(cut(unempl1$data[order],
