带NA的Lubridate问题

Question

为什么在解析这个日期时我会得到NA？

 library(lubridate)
 d2 <- "2015-Mar-07"
 ymd(d2)

 > NA

我不会在其他例子中发现失败。是因为Mar用西班牙语吗？我怎样才能强迫它解析日期？

我的地区设置：

> readr::locale()
<locale>
Numbers:  123,456.78
Formats:  %AD / %AT
Timezone: UTC
Encoding: UTF-8
<date_names>
Days:   Sunday (Sun), Monday (Mon), Tuesday (Tue), Wednesday (Wed), 
Thursday (Thu), Friday (Fri), Saturday (Sat)
Months: January (Jan), February (Feb), March (Mar), April (Apr), May 
(May), June (Jun), July (Jul), August (Aug),
    September (Sep), October (Oct), November (Nov), December (Dec)
AM/PM:  AM/PM

谢谢

这里一切都很好。您能检查一下您安装的lubridate版本吗？我在R3.6.3上有1.7.4节。

library(lubridate)
d2 <- "2015-Mar-07"
> ymd(d2)
[1] "2015-03-07"

或者，您可以使用基本R并强制格式：

d2 <- "2015-Mar-07"
d2new = as.Date(d2, format = "%Y-%b-%d")
> d2new
[1] "2015-03-07"
