Hola grupo, estoy siguiendo una gu?a de la librer?a rLandsat que me la he descargado de:
devtools::install_github("socialcopsdev/rLandsat")
Y tras hacer los siguiente (obviamente tengo me he registrado previamente en la api correspondiente):
product_id = c("LC08_L1TP_145049_20180301_20180308_01_T1",

Pregunta sobre rLandsat
...r pero cuando visualizo en un SIG me dice que no tiene referencia espacial y el tama?o de pixel es de 29.9 y no de 30 como originalmente era y eso mete ruido al modelo que estoy generando. Alguien me podr?a ayudar?

How can I map numbers to colours with raster?
...ow can I map numbers to colours
with raster? Please
require(raster)
conne <- file("C:\\lai.bin", "rb")
sd<- readBin(conne, integer(), size=1, n=360*720, signed=F)
y<-t(matrix((data=sd), ncol=360, nrow=720))
r = raster(y)
extent(r) = extent(c(xmn=-180,xmx=180,ymn=-90,ymx=90))
plot(r)

standardized residuals (rstandard & plot.lm) (PR#8468)
This bug is not quite fixed - the example from my original report now =
works using R-2.2.1, but
plot(Uniform, 6)
does not. The bug is due to
if (show[6]) {
ymx <- max(cook, na.rm =3D TRUE) * 1.025
g <- hatval/(1 - hatval) # Potential division by zero here #
plot(g, cook, xlim =3D c(0, max(g)), ylim =3D c(0, ymx),=20
main =3D main, xlab =3D "Leverage", ylab =3D "Cook's distance",=

colour by z value, persp in raster package
Hi all!
My question is how to colour pixels by z value in persp plot in raster package. Here is an example:
x <- seq(-1.95, 1.95, length = 30)
y <- seq(-1.95, 1.95, length = 35)
z <- outer(x, y, function(a,b) a*b^2)
r1 <- raster(nrows=35, ncols=30, xmn=0, xmx=30, ymn = 0, ymx = 35)
r1[] <- c(z)
persp(r1)
There already exist some function to produce persp plot for anothe classes, but I have no idea how deal with RasterLayer object.
Thanks all!

Adjusting coordinates in raster plots
Dear R-Help,
When plotting a raster object the origin (0,0) is placed in the center.
E.g. using:
library(raster)
mat = matrix(runif(100),10,10)
r <- raster(ncol=10, nrow=10)
values(r) <- mat
plot(r, main='Raster example',xlab="x",ylab="y")
Does anyone know how to adjust the coordinate system?
E.g. I would like to have 0,0 at the top left.
My naive approach

Cook-distance-type plot (vertical bars)
Hi,
Figure 13 of Emmanuel Paradis's "R for Beginners" was produced by termplot
working on an aov object. The lower right-hand plot is labelled "Cook's
distance plot", and I'd really like to produce a similar type of figure,
but in a totally different context. (I'm not even sure what this kind of
figure is called, perhaps an "impulse plot", where
