当我使用软件包ggfortify对DNA微阵列数据进行PCA分析时，它返回
“。f（.x [[i]]，...）中的错误：找不到对象'RNVU1'”
我该如何解决？
我的代码
library(ggfortify)
df <- as.data.frame(t(gset))
df$group <- group_list
autoplot(prcomp( df[,1:(ncol(df)-1)] ), data = df, colour= "group")
我的数据
head(group_list)
[1] "A375 cells 24h Control rep1" "A375 cells 24h Control rep2"
[3] "A375 cells 24h Control rep3" "A375 cells 24h Vemurafenib rep1"
[5] "A375 cells 24h Vemurafenib rep2" "A375 cells 24h Vemurafenib rep3"
