英文:
Error using predict function terra package in R
问题
I get an error when trying to perform a spatial prediction using a previously fitted GLM model and a SpatRaster containing the environmental predictors. Does anyone know what could be causing this error?
this is my code:
env <- rast("data/rasters/predictors.tif")cv_data <- SDM_list_new[[2477804]]$simple_glmpr_cur_prob <- terra::predict(env, cv_data, cores = 1, type = "response")#Error in .runModel(model, fun, d, nl, const, na.rm, index, ...) :# argument "cores" is missing, with no default
I have updated the terra package and also tried running the code with changing the number of the "cores" argument or omitting the cores argument, which did not help.

以下是您要翻译的部分：
无法回答您的问题，因为您没有提供一个最小的自包含可重现示例。我们也不知道您正在使用哪些其他包以及它们的版本是什么。我猜测这可能是由于其他包的干扰导致的。因此，我建议尝试在不加载不必要的包的情况下运行此代码（然后可能再次添加它们以查明问题出在哪里）。
以下代码（来自?terra::predict）对我来说可以正常运行：
library(terra)# terra 1.7.29logo <- rast(system.file("ex/logo.tif", package="terra"))names(logo) <- c("red", "green", "blue")p <- matrix(c(48, 48, 48, 53, 50, 46, 54, 70, 84, 85, 74, 84, 95, 85,66, 42, 26, 4, 19, 17, 7, 14, 26, 29, 39, 45, 51, 56, 46, 38, 31,22, 34, 60, 70, 73, 63, 46, 43, 28), ncol=2)a <- matrix(c(22, 33, 64, 85, 92, 94, 59, 27, 30, 64, 60, 33, 31, 9,99, 67, 15, 5, 4, 30, 8, 37, 42, 27, 19, 69, 60, 73, 3, 5, 21,37, 52, 70, 74, 9, 13, 4, 17, 47), ncol=2)xy <- rbind(cbind(1, p), cbind(0, a))e <- extract(logo, xy[,2:3])v <- data.frame(cbind(pa=xy[,1], e))model <- glm(formula=pa~., data=v)r0 <- predict(logo, model)r1 <- predict(logo, model, cores=1)r2 <- predict(logo, model, cores=2)
希望这对您有所帮助。

It is not possible to answer your question as you do not include a minimal self-contained reproducible example. We also do not know what other packages you are using, and what their versions are. I am guessing that this happens because of some interference from another package. So I would suggest trying this without loading packages that are not strictly needed (and then perhaps adding them again to see where things go wrong).
The below (from ?terra::predict) works fine for me.
library(terra)#terra 1.7.29logo <- rast(system.file("ex/logo.tif", package="terra"))names(logo) <- c("red", "green", "blue")p <- matrix(c(48, 48, 48, 53, 50, 46, 54, 70, 84, 85, 74, 84, 95, 85,66, 42, 26, 4, 19, 17, 7, 14, 26, 29, 39, 45, 51, 56, 46, 38, 31,22, 34, 60, 70, 73, 63, 46, 43, 28), ncol=2)a <- matrix(c(22, 33, 64, 85, 92, 94, 59, 27, 30, 64, 60, 33, 31, 9,99, 67, 15, 5, 4, 30, 8, 37, 42, 27, 19, 69, 60, 73, 3, 5, 21,37, 52, 70, 74, 9, 13, 4, 17, 47), ncol=2)xy <- rbind(cbind(1, p), cbind(0, a))e <- extract(logo, xy[,2:3])v <- data.frame(cbind(pa=xy[,1], e))model <- glm(formula=pa~., data=v)r0 <- predict(logo, model)r1 <- predict(logo, model, cores=1)r2 <- predict(logo, model, cores=2)
