Question

您好我在文件夹

中的许多文件上运行以下r脚本

runForAll <- function(x) {
  emboss <- read.table(x,header=T)
  x <- table(emboss[,2],emboss[,3])/NROW(emboss[,3])
  y <- as.vector(t(x))
  nms <- expand.grid(colnames(x), rownames(x))
  names(y) <- paste( nms[,2],nms[,1],sep="")
  return(t(y))
}
my.files <- list.files(pattern = "emboss_\\d+\\.ss")
outputs <- lapply(my.files, FUN = runForAll)

我注意到在x中，某些表的行比其他表少1行。

正常x：

我该如何检查：

x的每个实例有20行如果x的特定实例少于20行添加一个充满零的行

即如果一个x只有17行，则添加3行零。

非常感谢。

Answer 1

这样做：

x = data.frame(A = c(1:10), B = 1, C = 1)
x[head(seq(nrow(x)+1, 21), -1),] = 0

检查两个表，如果一个表的行数较少 - 然后添加行
