R中的meta包中的森林图

Question

我在元数据包中使用林函数，代码如下：

rm_md= metagen(data = df1, TE= Effect.Estimate,seTE = SE,studlab = Study,sm =  "MD",comb.fixed =FALSE, byvar = Subgroup)
forest(rm_md,overall = F,overall=FALSE,layout = "RevMan5",digits.se = 2,print.byvar = FALSE,
     leftcols = c("studlab","TE", "seTE","w.random","effect.ci"),
     leftlabs=c("Study","Mean Difference","SE","Weight","95% CI"))

并收到此错误：

Error in if (size > 0 && (convertX(unit(TE, "native") + unit(0.5 * size,  : 
missing value where TRUE/FALSE needed

它给出了曲线图，但对于某些学习正方形未显示。 找不到代码有什么问题吗？
