R lubridate-使用“应用”和“分钟”时出错

我有一个函数正在处理

lubridate

包中的

period

对象。具体地说，我使用

minute（）

函数时出错，而在apply内部使用minute，即：

apply（data，2，minute）

我编写的函数是一个包装器，在将周期对象转换为数字（秒数）后，使用

mean、sd等

。代码如下：

conv_ms <- function(x, func= "mean", na.rm=TRUE, ...) {
  # extract min/sec, convert to numeric
  m <- minute(x)
  s <- second(x)
  mns <- m * 60 + s
  # apply wrapper
  if (func == "mean") {
    x2 <- mean(mns, na.rm= na.rm)
  } else if (func == "sd") {
    x2 <- sd(mns, na.rm= na.rm)
  } else if (func == "median") {
    x2 <- median(mns, na.rm= na.rm) 
  } else if (func == "quantile") {
    x2 <- quantile(mns, na.rm= na.rm, ...)
  } else if (func == "min") {
    x2 <- min(mns, na.rm= na.rm)
  } else if (func == "max") {
    x2 <- max(mns, na.rm= na.rm)
  }
  m2 <- trunc(x2 / 60)
  s2 <- round((x2 - trunc(x2 / 60)) * 60, 0)
  return(ms(paste(as.character(m2), as.character(s2), sep=":")))
}

数据——编辑以使用dput

dput(men_g[,10:11])

与其粘贴数据输出，不如考虑使用

dput

制作一个可复制的示例。我确实考虑过。我认为用这种方式工作更容易。不？很高兴改变它。我还可以将数据放在GitHub上。@Thomas-编辑为使用

dput
