I've simulated this data.frame: library(plyr); library(ggplot2) count <- rev(seq(0, 500, 20)) tide <- seq(0, 5, length.out = length(count)) df <- data.frame(count, tide) count_sim <- unlist(llply(count, function(x) rnorm(20, x, 50))) count_sim_df <- data.frame(tide=rep(tide,each=20), count_sim) And it can be plotted like this:…
Is there a way (using ggplot or some other package maybe) to angle the labels of a pie chart in R? For example, this code (using R defaults): data <- c(4,9,2,5) names <- c("alpha","beta","gamma","delta") pie(data,names) Creates this pie chart: What…
This code produces the first plot below: water.height <- seq(0, 5, 1) y <- seq(0, 1500, length.out = 6) df <- data.frame(water.height, y) library(ggplot2) ggplot(df, aes(water.height, y)) + geom_blank()+ theme_bw() I have photoshopped in this blue background: Can I produce…
I can not find a solution for my overplotting problem. If somebody could help me find a solution I would appreciate that a lot. My data look like this (csv format): http://pastebin.com/embed_js.php?i=Cnfpkjsz This is the code I am running: library(dplyr)…

I'm new to regex (and stackoverflow btw) and trying to extract "real" words out of this using R: "nnnclonenstarnnnnnbrainnstarnnnnncalculatornstarnnnnnadding machinenstarnnnnnartificial intelligencenstar" So i would like to match: clone, brain, calculator, adding machine, artificial intelligence. I tried it with (?<=\n)(.*?)(?=\nstar) which…
First of all, I'm still a beginner. I'm trying to interpret and draw a stack bar plot with R. I already took a look at a number of answers but some were not specific to my case and others I…
