我正在使用omu软件包进行代谢物分析。我有一个计数数据文件和元数据文件。软件包的omu_summary函数对计数文件执行t检验，如下所示：
DF_stats <- omu_summary(count_data = DF, metadata = meta.data, numerator = "Summer",
denominator = "Winter", response_variable = "Metabolite", Factor = "Treatment",
log_transform = TRUE, p_adjust = "BH")
执行函数时引发以下错误：
if（stderr <10 * .Machine $ double.eps * max（abs（mx）， abs（my）））stop（“数据本质上是恒定的”）：缺少值 需要TRUE / FALSE的地方
str（DF）返回：
Classes 'cpd' and 'data.frame': 1340 obs. of 11 variables:
$ Metabolite: chr "Pilocereine" "Quercetin 3-(2G-xylosylrutinoside)" "Cyanidin 3-O-(6''-glucosyl-2''-xylosylgalactoside)" "Troxerutin" ...

测试是否在W1，W2，S1和S2上执行，这似乎是数字。我该如何解决这个问题？
