Basic Info. requried

I believe there is a mistake in your command. You skipped the "raster"
command itself. From the raster help files here is the correct way:

r <- raster(system.file("external/test.grd", package="raster"))

I want to read Iknos image and then want to see display in R. Just read and
display nothing else.
I try using raster package

rasterfile<-system.file("C:/iknos/edwards_airbase_usa_1m_tc.tif",package="raster")

Then plot with the help of this command

plot(rasterfile)

Error in plot.window(...) : need finite 'ylim' values
In addition: Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf

Need help from where I can learn basic things, I already read raster
package manual but unable to see the image.
