    How to plot non-parametric data with multiple time points?

    Hello, I analyzed some physiologic data (blood electrolyte levels etc) which was fairly skewed, so I used Kruskal-Wallis to test for differences between groups. I originally plotted the mean and SD, but I learned that plotting the median is more suitable with skewed data. My question is...

    Base R: add points() in a loop defined by group

    Dear all, I am looking for a way to generate different plots in base R with adding points and lines manually to the plot. Here is my sample data: xy <- data.frame(NAME=c("NAME1","NAME1","NAME2","NAME2"), X_START_YEAR=c(1984,1986,1899,1903)...

    Build a graph using R

    I need to build this graph, So i have this formula: k <- 0 maxthreshold <- 100000 thresholds <- c() points <- c() while (k < maxthreshold){ inmb <- k*DELTA_QALY - DELTA_COST k <- k+100 } So what i need is that in the x axes to put different values of k and in the y...
