Question

我正在使用:R x64，并且不能运行我的代码，我不知道是什么问题。嗨，开发人员，这是我的代码，我有错误，我不知道是什么问题：

ncix <- read.table("nci.csv", sep = ",", row.names = 1, header = TRUE)
nciy <- read.table("ncilabel.txt", header = FALSE)
dat2 <- t(ncix)
dim(ncix)
dim(dat2)
mat <- matrix(rep(0,64*6831),nrow = 64)
for (i in 1:64){
   mat[i,]<-c(nciy[i,], ncix[,i])
}
data <- data.frame(mat)
View(data)
data$Y <- factor(data$X1)
levels(data$Y)<-c("BREAST", "CNS", "COLON", "K562A-repro", "K562B-repro", "LEUKEMIA", "MCF7A- 
repro","MCF7D-repro","MELANOMA","NSCLC","OVARIAN", "PROSTATE", "RENAL","UNKNOWN")
data$X1<-NULL
table(data$Y)
oui <-c("BREAST", "CNS", "COLON", "LEUKEMIA", "MELANOMA", "NSCLC", "OVARIAN", "PROSTATE", "RENAL")
dat2 <- data[data$Y%in%oui,]
mat2 <- mat[data$Y%in%oui,]
res.pca =PCA(dat2, scale.unit=TRUE, quali.sup=6831, ncp=12)

以下是错误代码：

 res.pca =PCA(dat2, scale.unit=TRUE, quali.sup=6831, ncp=12)
 Error in PCA(dat2, scale.unit = TRUE, quali.sup = 6831, ncp = 12) :

这是正确的代码，非常感谢：
