tar: Failed to set default locale

Hi,

A simple question. I run the script from https://github.com/TaiwanRUserGroup/DSC2014Tutorial on my Mac OS X.
But I get many messages like this "tar: Failed to set default locale"
And also the warning:
"Warning messages:
1: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called 'whisker'
2: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called 'ggvis'
3: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called 'e1071'
4: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called 'caret'
5: In library(package, lib.loc = lib.loc, character.only = TRUE, logical.return = TRUE, :
there is no package called 'randomForest'"

Is this OK or I need to do something else to make sure "DSC2014Tutorial" is fine on my Mac?

Thank you

有些套件過於老舊以至於安裝DSC2014Tutorial失敗

因為這是屬於套件安裝的部份，所以issue還是開在這裡了

問題出在user的scales底下的munsell的colorspace過於老舊

是否在安裝套件前先執行個update指令？

Basci_file

需要幫Basic製作helper function

Basic Visualization更新

在https://github.com/KuiMing/graphics
更新了投影片和salary.RData，salary.RData在WINDOWS的中文編碼問題還是得請WUSH大大幫忙一下，應該跟之前一樣處理即可。

另外新增df_browser.RData，此檔無中文。

windows 8.1 安裝失敗

Jerry 回報，加入 type = "win.binary" 會導致安裝失敗。

taiwanrusergroup.github.io not found

deps <- available.packages("http://taiwanrusergroup.github.io/R/src/contrib")[1,"Imports"]

參照的packages url失效了，有辦法更新嗎？

add ubuntu package espeak: an alternative package to "say" command in MAC

please add espeak to ubuntu pre-installation command: (in README file)
replace

sudo apt-get install libcurl4-openssl-dev libxml2-dev

with

sudo apt-get install libcurl4-openssl-dev libxml2-dev espeak

reshape package 沒包到

reshape2 裡面的dcast 在windows系統下沒辦法用中文參數，建議改用reshape裡面的cast (Data Analysis)

DataAnalysis 的第六頁code噴掉

slides("Basic") 導向舊版投影片

而不是 RBasic_Revised 的版本

package slam install error (on WIN 7)

建議在一開始的Markdown中新增 R更新的方法

windows

參考資料
在R console鍵入

install.packages("installr"); require(installr) 
updateR()

Ubuntu

參考資料

移除舊版的R

在ubuntu指令列中鍵入

sudo apt-get remove r-base-core

手動更新sources.list

sudo gedit /etc/apt/sources.list

增加下列文字

deb http://cran.rstudio.com/bin/linux/ubuntu trusty/

新增Public Keys

gpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9
gpg -a --export E084DAB9 | sudo apt-key add -

安裝新版R

sudo apt-get update
sudo apt-get install r-base

做完直接開啟R檢查版本即可

需要Vis_file

Ttop if the locale is not one of them.
