R Package install order automation

There is a bioconductor tool to generate install order for packages [here].
Initially tool generates graph of CRAN package dependencies (ignoring suggests, because otherwise graph will be acyclic).


Usage Example:

source("http://www.bioconductor.org/biocLite.R")
biocLite("pkgDepTools")
require('pkgDepTools')
deps <- makeDepGraph("http://cran.r-project.org", type="source")
a<-getInstallOrder("plyr",
deps,needed.only=FALSE)
a$packages
[1] "iterators" "itertools" "plyr"

Ant task with wildcard expansion for svn.

Ant is a popular tool among Java developers but one can use it for some other generic tasks. For example using svn as a task inside an ant script is provided by a library. However wildcard expansion won't work under this task. One way to over come this to use an exec task as follows (in windowz):
<exec executable="cmd.exe">
<arg line=" /C svn --force delete pathtofiles\*.dat
--username=username --password=password">
</arg>
</exec>
