Hello everyone, I want to plot a "greater than" symbol (the "_" under ">") on the x-axis in the labels. Is it possible to do it? Thanks. Bingshan [[alternative HTML version deleted]]

Hi there, I have a dataframe whose elements are numbers or characters. I want to extract the frequencies of each elements in the dataframe. For example, d = as.data.frame(matrix(c(1, 2, 3, 3), 2,2)) What I want is first what are the elements in the data (1,2,3 here) and second what are their frequencies (1,1,2 respectively). How to use "table" to extract these two pieces of

Hi all, I have a vector and want to merge its elements one by one into a single string or number. For example, x=c(1,2,3), what I want is a new number 123. I used "paste" but it just output "1" "2" "3" which is not what I want. Is there any way to do this? Thanks!

Hello everyone, I have a variable with several categories and I want to convert this into dummy variables and do logistic regression on it. I used model.matrix to create dummy variables but it always picked the smallest one as the reference. For example, model.matrix(~.,data=as.data.frame(letters[1:5])) will code 'a' as '0 0 0 0'. But I want to code another category as

Hi there, I have the following plot. The circles and the line do not cross in the main plot. But in the legend, the circle and the line cross. I am wondering if there is a way to make the legend look like the plot without crossing. I looked around but did not find a way to do that. Is it doable? plot(x,x^1.5, pch=1, lty=1, type='b') legend(1,25, legend="hello",pch=1,

Hi, all, I am wondering if there is an algorithm for calculating power of 2x3 table using Fisher exact test. There is one (algorithm 280) for 2x2 Fisher exact test but I couldn't find one for 2x3 table. If we are not lucky enough to have one, is there any other way to calculate exact power of 2x3 table? The reason why I want exact power is because some cells are assumed to be very
