David's almost works except it catches the MONTH column, just add an empty metacharacter tho. c(DAY, MONTH, YEAR, SA_TUES, SA_MON, SU_WED, CH_TUES, CH_WED, CH_MON, AR_TUES, AR_WED, AR_MON, SA_THUR, SU_FRI, CH_THUR, CH_FRI, AR_THUR, AR_FRI)- columns sa_ind - grep(SA_,columns) days - gsub(SA_,,

Does this resemble what you're after? library(reshape2) tst - melt(testdataset) library(ggplot2) ggplot(tst, aes(x=Var1, y=Var2, fill=value)) + geom_tile() + scale_fill_gradient2(low=white, high=white, mid=scales::muted(blue), midpoint=0.6148377) On Wed, Sep 24, 2014 at 10:26

Re: [R] Legend in ggplot2

2014-08-07 Thread Federico Lasa
The problem is that you are not actually 'mapping' any variables to the fill and colour aestethics so ggplot wont produce legends for those. I'm not sure ggplots are appropiate for what you're trying to do here but you can sure hack around it a bit, for instance try: ggplot(tabu, aes(x=weeks,

Re: [R] Does a survival probability(the probability not experiencing an event) have to be non-increasing?

2014-03-19 Thread Federico Lasa
Don't really understand your equations but. If X is the (random variable of) time of event, then the survival S(x) = 1 - Pr( X x ) has to be non increasing since: If t1 t2. then S(t1) - S(t2) = Pr(X t2) - Pr( X t1 ) = Pr( t1 X t2) 0 which means that S(t1) S(t2). But you must not

Hi, chiming in. Pasted the code in R studio and the format parser wouldn't mark the R code chunks. It was because there were line breaks in the middle of chunk options tags. Couldn't test if removing line breaks works, but maybe that's the source of the problem? On Mon, Dec 23, 2013 at 10:37
