Hello Friends, I am new to R and stuck with a problem.
i have two columns drug_A and drug_B, i have plotted a scatter plot using the ggplot2 function. My problem is with the third column, it is the p-value column. I want to color and size points differently based on the p_value, the p_value range is between 0<0.0001< 0.001<0.05<1. I used a script using the ifelse loop, but it considers only two conditions at one time. Please tell me a way to fulfill all the conditions. here is the script: library(lattice) qplot(Drug_A, Drug_B, data=dsmall, size = p_value, colour = ifelse(p_value > 0, ">0", "<0.0001"), + ifelse(p_value1 > 0.001, ">0.001", "<0.01") + ifelse(p_value1 > 0.001, ">0.001", "<0.05" )) ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
