Hello all, Need some suggestions on interesting use cases with R in the field of log processing. Any help would be greatly appreciated. -- With Thanks and Regards, Ramprakash Ramamoorthy, India, +91 9626975420 [[alternative HTML version deleted]]

...posts on the r-help system and I feel compelled to quickly admit that I am relatively new to R, I do have several reference books around me, but I cannot count myself among the fortunate who seem to strong programming intuition. I have a data set consisting of 1637 observations of five variables: tensile strength, yield strength, elongation, hardness and a character indicator with three levels: (Y)es, (N)o, and (F)ail. My objective is to randomly sample various subsets from this data set and then evaluate these subsets using simple parameters among them tests for normality, shape and skewness. Th...

...sed on R. My code also allows for a graphical visualization of weibull fitted data. In particular, data can be represented by a straight line in a so-called Weibull plot. According to my observations this is the most common way of analyzing Weibull distributed data (e.g. time to breakdown values, tensile strength values, metal fatigue). Here comes my code: # data 4 wbl plot data<-c(10,25,35,90,175) confidence_level=.95 jpeg() library(survival) # time to breakdown values res<-survreg(Surv(data) ~ 1,dist='weibull') # scale parameter: eta=exp(res$coefficient) # shape paramet...
