我正在使用 R 包中的ncdc 功能rnoaa来下载一个站的降雨数据
这是代码：
start_date <- "1895-01-01"
end_date <- "1895-12-31"
datatype <- "PRCP"
siteNumber <- "GHCND:USC00023498"
data <- ncdc(datasetid='GHCND', stationid=siteNumber[j], datatypeid=datatype, startdate = start_date, enddate = end_date)$data
我查了一下，这个站的数据直到 1895-07-31，但我得到的输出只到 1895-01-25：
> dput(data)
structure(list(date = c("1895-01-01T00:00:00", "1895-01-02T00:00:00",

我也尝试过其他年份，但我遇到了同样的问题，只下载了第一个月的数据。
我的代码有问题吗？（我在其他场合使用过这个功能，并且工作正常）
