> write.table(IL2.ZAvsIL2_GSEA, file="IL2.ZAvsIL2_GSEA.txt",row.names = FALSE,sep = "\t")

由于“描述”中的“NA”，Java看起来会引发格式错误。专栏，但我不知道如何纠正这个问题。

Answer 1

解析器区分大小写。将“NA”更改为“na”以修复，例如

write.table(IL2.ZAvsIL2_GSEA, file="IL2.ZAvsIL2_GSEA.txt",row.names = FALSE,sep = "\t", na.strings = "na")

Answer 2

我也遇到了同样的问题，即使使用A.liberzon提到的“ na”把戏，仍然遇到错误。我继续将数字值放在“说明”列中（即df$Description <- 1），然后就可以正常加载了。

将txt文件加载到GSEA
