我试图在线性回归模型中创建两个变量对结果变量的交互影响图plot_model。我的模型中有一个交互项 (BLK70*FP59)，但是当我使用时，type = "int"我得到“错误：模型中没有找到交互项”。
我可以得到我想要使用的情节type = "pred"，但我想在交互中更改主持人术语（下面的 FP59）的值。我怎样才能做到这一点？请参见下面的示例：
library(sjPlot)
model1 <- lm(HR70 ~ . - NAME - STATE_NAME,
data = crimeExFilt)
model2 <- update(model1, ~ . - PO60 - PO70 -
HC60 - HC70 - POL60 - POL70 -
RD60 - RD70 - PS60 - PS70)
model3 <- update(model2, ~ . - GI69)
model4 <- update(model3, ~ . - GI59)
model5 <- update(model4, ~ . - MFIL59)
model6 <- update(model5, ~ . - FP69)
model7 <- update(model6, ~ . - FH60)
model8 <- update(model7, ~ . - DV60)
model9 <- update(model8, ~ . - UE60)
model10 <- update(model9, ~ . - DNL70)
model11 <- update(model10, ~ . - DNL60)
model12 <- update(model11, ~ . - BLK60)
model13 <- update(model12, ~ . - UE70)
model14 <- update(model13, ~ . + BLK70*FP59)
plot_model(model14, type = "pred", terms = c("BLK70", "FP59"))
在plot_model文档中我可以看到该mdrt.values功能，但这不适用于type = "pred".
另外，如何为 FP59 的不同值添加更多行？
编辑：摘要数据来自以下dput(head(crimeExFilt, 20))。我删除了一个变量（名称），因为它与模型无关，而且我超出了字符数。
