R: for installing package 'RODBC'

Today, i try to install a package in R named 'DOBDC', while i meet a message:

> install.packages('RODBC')

package ‘RODBC’ is available as a source package but not as a binary

警告信息：
package ‘RODBC’ is not available (for R version 3.1.2)

Then, i opened 'R package installer', choosed 'CRAN(sources)' and enter 'RODBC' for searching.

Greatfully, there comed a package named 'RODBC', I enter 'install Selected' quickly. (choose 'install dependencies')

After a moment, R told me that it had put it in this:

下载的程序包在
‘/private/var/folders/y2/gh_0bmkn42qbgvj7hjjvtjb40000gn/T/RtmpkO2JlR/downloaded_packages’里

I opened it up and saw it. I wrote these into R:

> install.packages('RODBC_1.3-10.tar.gz',repos=NULL,tpye='source')
错误: 文件‘RODBC_1.3-10.tar.gz’不是OS ​​X的二进制软件包

Pay attention here:

i have tried to use Rstudio to install 'RODBC' by 'install packages' in 'Tool', while it still gives me:

> install.packages("RODBC")

package ‘RODBC’ is available as a source package but not as a binary

Warning in install.packages :
package ‘RODBC’ is not available (for R version 3.1.2)

so , i have to ues R Console again.

Question is what I can do now.

e.g. seceed install as:

> install.packages('animation')
试开URL’http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/animation_2.3.tgz'
Content type 'application/x-gzip' length 460758 bytes (449 Kb)
打开了URL
==================================================
downloaded 449 Kb

The downloaded binary packages are in
/var/folders/y2/gh_0bmkn42qbgvj7hjjvtjb40000gn/T//Rtmp4p2EbR/downloaded_packages
> library(animation)
>

haha! i have find a way to solve last question, that is,

open 'R Package Installer' in 'packages & data'. i choose 'local source package' under 'Packages Repository', enter 'install...'. R  will tell us to choose a package. here i choose the package i just download before:

下载的程序包在
‘/private/var/folders/y2/gh_0bmkn42qbgvj7hjjvtjb40000gn/T/RtmpkO2JlR/downloaded_packages’里

Then, it works!!!!!!!!

I think every time i meet the problem about this , i can solve them as the same way.

i have meet the followint problem too. Make sure u have solved them.

some importance:

I had the same problem ("ODBC headers sql.h and sqlext.h not found") on OS X, and fixed it by installing unixodbc (brew install unixodbc)
