使用R軟件包MuMIn(v1.9.5)和命令dredge
時,beta = TRUE
切換器不再按預期運行。無法使用MuMIn軟件包返回貝爾係數R
# load Cement data set with MuMIn package
data(Cement)
# build global model
fmd <- lm(y ~ X1 + X2 + X3 + X4, data = Cement)
# dredge global model without returning standardized coefficients (default);
# WORKING
ms1 <- dredge(fmd)
# dredge global model and return standardized coefficients;
# NOT WORKING
ms1 <- dredge(fmd, beta = TRUE)
後者返回:
Error in dimnames(ret) <- list(names(model$coefficients), c("Estimate", :
length of 'dimnames' [1] not equal to array extent
基於R V3.0.0
