I want to use R for some statistical analysis of logfile information, but found that even the "limited" R-core RPM has a lot of dependencies not already installed. I don't want to install so many packages for a peripheral need.
Are there lightweight alternatives for simple statistical analysis on RHEL 6? I have an R script that accepts on stdin a large set of values -- one value per line -- and prints out the min, max, mean, median, 95th percentile, and standard deviation.
For more context, I'm using grep and awk to find GET requests for a particular path in our webserver log files, get the response times, and calculate the metrics listed above in order to measure the impact on performance of changes to a web application.
I don't need any graphing capabilities, just simple computation. Is there something I've overlooked?
