Hi, This is a simple version of something that I am trying to do. If I can sort the problem basically, I figure I should be able to sort it for the program I'm writing (which would take longer to explain). I need to know if there is any way of using different colours for different intervals of a line on a graph. Eg. If I plot the line y=x for x=1:10, and split this line into 106 intervals

Hi dear all, the following code is correct. but I want to use non-numeric x-axis, for example if I replace time <- seq(0,72,6) by month <- c("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec","Pag") Ofcourse I use factor(month) instead of

P.S. I am aware of the criticisms of these sort of graphs, but they are pretty. Also, they seem to be used a lot in meetings i've attended recently.

Hello R-world, Please, help me to get round my little mess I have a data.frame in which I'd rather like some values to be NA for the future imputation process. I've come up with the following piece of code: random.del <- function (x, n.keeprows, del.percent){ n.items <- ncol(x) k <- n.items*(del.percent/100) x.del <- x for (i in (n.keeprows+1):nrow(x)){ j <-

Hello Dimitris, I was goggling for some help on Sensitivity vs 1-specificity and saw your link. I hope you can be of help to me in one of the issue that I am facing in generating combo chart(bar chart and plot). I am a novice and have some difficulty in getting this logic correct. I am give a dataset (I am attaching a sample dataset). I am using a barplot() and passing values for

How can I use row.names() as y-labels in Dotplot? How to set horizontal orientation for y-lables in lattice()? Dotplot(stcod1 ~ Cbind(statgh2,statgh2-1.96*segh2,statgh2+1.96*segh2)[og], subset=statgh2[og]>0.1, data=h2inqerrg02st, xlab="G", ylab=row.names(h2inqerrg02st)[og], main="") I have tried doing it with mtext() as well, but there is not enough space besides

Oh sorry. An example say lots more than words. The data below, when submitted to twoord.plot return the mentioned error. Rain are bars and Salt lines, the bars appear and the error occurs with the salt data.
