Cada vez que intento cargar el paquete "agricolae" me da el siguiente mensaje: Error: package or namespace load failed for 'agricolae' in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]): there is no package called 'spData' He intentado todo actualizar los paquetes, volverlos a instalar pero no hay forma. Si sabeis la solución ?? Un saludo. Juan Bautista Relloso Barrio ------------ próxima parte ------------ A non-text attachment was scrubbed...

Hello, I am running an ARMA model to run forecast for changes in S&P 500 prices. My ARMA calculations look as follows armacal <- arma( spdata, order = c(0,4), lag = list(ma = c(1,2,4)) ) Output: Call: arma(x = spdata, order = c(0, 4), lag = list(ma = c(1, 2, 4)) ) Coefficient(s): ma1 ma2 ma4 intercept -0.073868 0.058020 -0.081292 0.007082 All's bright and sunny till this point...after this it gets st...

...structure (such as "corExp" or "corGaus") works. Let me use the example and data posted on UCLA's R FAQ webpage to explain my problems. The link for the webpage is: http://www.ats.ucla.edu/stat/r/faq/spatial_regression.htm install.packages("nlme") library(nlme) spdata <- read.table("http://www.ats.ucla.edu/stat/R/faq/thick.csv", header = T, sep = ",") dummy <- rep(1, 75) spdata <- cbind(spdata, dummy) ### estimate the null model ### soil.model <- lme(fixed = thick ~ soil, data = spdata, random = ~ 1 | dummy, method = "ML&quo...

I need to perform a QR-decomposition of a sparse matrix, so I've been trying to use the Matrix package. Unfortunately I don't seem to be getting exactly the same results as if I had used the qr() command from the base package. Here is an example of what I'm doing. > spdata <-rpois(50,1) > y <- rnorm(10,0,1) > S <- matrix(round(ifelse(spdata==0,0,1/spdata),2),ncol=5,nrow=10) > Ssp <- as(S,"sparseMatrix") > > decomp <- qr(S) > Y <- qr.qty(decomp,y) > R <- qr.R(decomp) > > decompSp <- qr(Ssp) > Ysp <- qr...
