[R] How can I avoid the warning messages when calling DAAG package?
Dear R users, I'm a newbie for R and want to ask some basic questions. So, after I open the R software, I typed library(DAAG). Then, I get massive warning messages as shown below. Why does it happen? Also, here are few specific questions regarding each message. 1) Loading required package: MASS -> Does this mean that the MASS package is not included in DAAG? 2) Attaching package: 'survival' ->Does this also mean that the package 'survival' is attached because it is not included in DAAG? 3) Why are so many objects masked even after I open up the fresh R and type library (DAAG) first time? Any help would be appreciated, Jason> library(DAAG)Loading required package: MASS Loading required package: rpart Loading required package: randomForest randomForest 4.6-6 Type rfNews() to see new features/changes/bug fixes. Loading required package: boot Loading required package: survival Loading required package: splines Attaching package: ‘survival’ The following object(s) are masked from ‘package:boot’: aml Attaching package: ‘DAAG’ The following object(s) are masked _by_ ‘.GlobalEnv’: fossilfuel The following object(s) are masked from ‘package:survival’: lung The following object(s) are masked from ‘package:MASS’: hills [[alternative HTML version deleted]]

Next, DAAG is masking some objects from the other packages. Since we have NAMESPACES nowadays, it is not too serious to mask objects unless you want to use them directly (and the information is given to notify you about that).
