lme()函数,错误:C堆栈使用率7969204太接近极限

我正在尝试使用lme()函数进行重复测量回归(结果是一个连续变量" asdate_regdate")。首先,我发布了这个问题,因为我在f1行之后收到了错误。问题解决了,我在lme行后面临一个新的错误。

我有30个变量和66872行数据。我有分类和数字预测器。我每个病人都有多行数据。 " IKN"是每个患者的ID变量。我替换了数据集中的缺失值,我在两个变量中只有少量缺失数据,这就是我使用na.action = na.omit的原因。当我运行代码时,我在lme函数后收到以下错误。

错误:C堆栈使用率7969204太接近极限。

我的代码如下:

vars1 <- colnames(d.train)[-c(1,30)]

f1 <- as.formula(paste("asdate_regdate~", paste(vars1, collapse= "*")))
f2 <- as.formula(paste("~1|ikn"))

library(nlme)
model <- lme(f1, random=f2, data=d.train, method="ML", na.action=na.omit)

请找到colnames(d.train)如下:
