search for: precentage

hi all i have found the follwoing way to choose a random sample by sample size (200): ten_per_T2000 <- F_T2000_All[sample(nrow(F_T2000_All), 200), ] but i wondered if there is a way to choose a sample size by precentage (10% etc..) thx ethan

Hi, I am looking for an elegant way to transform a vector into percentages of values that meet certain criteria. store<-c(1,1.4,3,1.1,0.3,0.6,4,5) # now I want to get the precentages of values # that fall into the categories <=M , >M & <=N , >N # let M <-.8 N <- 1.2 # In my real example I have many more of these cutoff-points # What I did is: out <- matrix(NA,1,3) out[1,1] <- ( (sum(store<=M )) /length(store) )*100 out[1,2]...

Dear all, I am trying to calculate some measure of the amount of variability in the response variable that is explained by a model fitted in lmer m1<-lmer(response-var ~ Condition+(1|Site/Area/Transect),family="binomial") . I've seen from the literature that the precentage of explained deviance is a common measure. How can I calculate it? Thanks a lot for your help, I hope this is not too shallow.

....12) I've struck a problem drawing barcharts after installing R 2.0.0. Previously I've used the following command print(barchart(100*result ~ sample, groups=congener, data=dioxin.2003.fresh.ub.p, stack=TRUE, ylim=c(0,102))) to draw a stacked barchart of the precentage contribution of each type of dioxin congener. Now, however I get the following error. Error in grid.Call.graphics("L_rect", x$x, x$y, x$width, x$height, valid.just(x$just)) : invalid line type The graph that actually results on my trellis device has axes and for the first sample it ma...
