从混合模型图中替换 x 轴

Question

在我下面的情节中，我想知道我是否可以将 grade 作为 x 轴？

multivariate <- read.csv('https://raw.githubusercontent.com/hkil/m/master/bv.csv')

library(nlme)
library(effects) # for plot

m2 <- lme(var ~ 0 + d_math + d_hyp + d_math:I(grade-2) + d_hyp:I(grade-2),
          random = ~ 0 + d_math + d_hyp + d_math:I(grade-2) + d_hyp:I(grade-2) | id, data = multivariate,
          na.action = na.omit, weights = varIdent(c(hyp=.3), form = ~1|grp),
          control = lmeControl(maxIter = 200, msMaxIter = 200, niterEM = 50,
                               msMaxEval = 400))

plot(allEffects(m2), multiline = TRUE)

Answer 1

应该这样做：

plot(allEffects(m2), x.var="grade", multiline = TRUE)

从混合模型图中替换 x 轴

Replace x-axis from a mixed-model plot
