r - 错误：替换有 x 行，数据有 y

Question

我正在从 Java 运行这个 R 脚本（我正在使用 Renjin）：

getCoefficients <- function(x, y, Regions) {
  nbRegions <- length(Regions)
  lengthY <- length(y)
  colRegions <- NULL
  from <- 1
  to <- lengthY / nbRegions
  for (i in 1:nbRegions) {
    region <- Regions[i]
    c <- cbind(region, from:to)
    colRegions <- rbind(colRegions, c)
  }
  indexCols <- as.data.frame(colRegions)
  x_ <- t(x)
  data_ <- cbind(indexCols, y, x_)
  dataFrame <- data.frame(data_)
  colnames(dataFrame) <- c("region", "date", "y", "a", "b", "c", "d", "e", "f", "r", "o")
  print(colnames(dataFrame))
  model_RE_S <- try(plm(y ~ x_, data = dataFrame, model = "random", index = c("region", "date"), effect = "twoways"))
  summryModel <- summary(model_RE_S)
  coeff <- as.numeric(summryModel$coefficients)
  #print(summryModel)
  
  return(coeff)
}

我收到以下错误，我不知道如何解决它：

Error : replacement has 3648 rows, data has 456

x 是 456 8 矩阵，y 是 456 1 和 3 个区域。

**更新：另一种选择：** 我摆脱了 Renjin 并改用了Rserve。
