R 将calc与堆叠光栅砖一起使用

R 将calc与堆叠光栅砖一起使用,r,raster,lm,R,Raster,Lm,我试图在R中的两块光栅砖上运行一个线性模型。这两块砖来自不同的来源,但据我所知,它们具有相同的尺寸(lon、lat、time)。我得到了错误:“dimnames(x)中的错误发生后,你能显示s和traceback()的输出吗?只是添加了它们。不知道如何最好地显示,因为它是一个大的光栅堆栈,但我添加了头。请告诉我是否有更好的方法。 #stack two raster bricks s <- stack(rasterbrick1, rasterbrick2) fun=function(x)
