我正在尝试使用hydroplotpackage hydroTSM，但出现以下错误：

Error in UseMethod("time<-") : no applicable method for 'time<-' applied to an object of class "zoo"

我用过这段代码：

    td<-seq(as.Date("2009/02/12"), as.Date("2013/07/11"), "days") 
    Tempzoo = zoo(x=Temp, order.by=td)

    hydroplot(Tempzoo, na.rm=TRUE, ptype="ts+boxplot+hist", pfreq="dma",                      
      var.type="Temperature", var.unit="units", main=NULL, xlab="Time", ylab="Temp",
      win.len1=0, win.len2=0, tick.tstep="auto", lab.tstep="auto", 
      lab.fmt=NULL, cex=0.3, cex.main=1.3, cex.lab=1.3, cex.axis=1.3, 
      col=c("blue", "lightblue", "lightblue"), stype="default", season.names=c("Winter", "Spring", "Summer", "Autumn"), 
      h=NULL)

以下是我的数据集的一个子集：

我搜索了您的错误消息，并尝试了@Roland 提供的解决方案。timeSeries是的，当您尝试绘图时，似乎已经加载了包。这是一个例子：

library(zoo)
library(hydroTSM)

# create data
td <- seq(as.Date("2009/02/12"), as.Date("2013/07/11"), "days") 
n <- length(td)
Temp <- sample(c(rnorm(n, mean = 10), rep(NA, n/5)), n)
Tempzoo <- zoo(x = Temp, order.by = td)


# in addition, load the suspected package ‘timeSeries’ 
library(timeSeries)
# Attaching package: ‘timeSeries’
# 
# The following object is masked from ‘package:zoo’:
#   
#   time<-

# try plot
hydroplot(x = Tempzoo,
          na.rm = TRUE,
          ptype = "ts+boxplot+hist",
          pfreq = "dma",                      
          var.type = "Temperature",
          var.unit = "units",
          main = NULL,
          xlab = "Time", ylab = "Temp",
          win.len1 = 0, win.len2 = 0,
          tick.tstep = "auto", lab.tstep = "auto", 
          lab.fmt = NULL,
          cex = 0.3, cex.main = 1.3, cex.lab = 1.3, cex.axis = 1.3, 
          col=c("blue", "lightblue", "lightblue"), stype="default",
          season.names = c("Winter", "Spring", "Summer", "Autumn"), 
          h=NULL)

# Error in UseMethod("time<-") : 
#   no applicable method for 'time<-' applied to an object of class "zoo"

# i.e. your error

# detach ‘timeSeries’ 
detach(package:timeSeries)

# plot again
