安裝Zoo for R似乎是成功的，但給出'Error object'zoo'not found

Question

我似乎無法安裝zoo庫。我已經安裝了ggplot2，xts和許多其他庫。動物園是第一個拋出錯誤的人。

以下情況如何發生？

> install.packages("zoo") 
trying URL 'http://cran.mirrors.hoobly.com/bin/macosx/mavericks/contrib/3.1/zoo_1.7-11.tgz' 
Content type 'application/x-gzip' length 868268 bytes (847 Kb)

==================================================

The downloaded binary packages are in 
    /var/folders/7q/9z1s0pvd50qf30y7swrlpt_r0000gn/T//RtmpGPYn7C/downloaded_packages 
> zoo 
Error: object 'zoo' not found

仍然是R的noob。安裝後，您必須記住將庫導入到您的環境中。

# Install a library. 
install.packages("zoo") 

# Import it it into your script. 
library(zoo)
