title: "reached elapsed time limit" errors in R
body: <p>I keep getting "reached elapsed time limit" errors in R. I'm using studio. </p>
  
  <p>This is the code I am trying to run, a simple graph in ggplot:</p>
  
  <pre><code>require(ggplot2)
  docgraph &lt;- ggplot(data = plotnvto, aes(calluna, doc)) + 
    geom_point(aes(x = calluna, y = doc, color = "calluna"), size = 3) + 
    geom_point(aes(x = sedge, y = doc, colour = "sedge"), size = 3) +
    geom_smooth(aes(calluna,doc), method=lm, se=FALSE, color = "purple") +
    geom_smooth(aes(sedge,doc), method=lm, se=FALSE, color = "green") +
    scale_colour_manual("", 
                        values = c("calluna"="purple", "sedge"="green")) +
    labs(x= "Percent Cover", y= "DOC (mg/L)") +
    annotate(geom="text", x=10, y=36, label="y = -0.4498x + 26.6843
  R² = 0.1836, p = 0.1646",color="purple") +
    annotate(geom="text", x=30, y=36, label="y = -0.5058x + 16.0603
  R² = 0.1026, p = 0.3012",color="darkgreen") +
    theme_bw() +
    xlim(0,60) +
    ylim(0,50)
  docgraph  
  </code></pre>
  
  <p>Everytime I run it, I get an error message about reaching the elapsed time limit. Every time it does this, something is missing from the graph, whether this is the legend, axes, grid lines, dots, colours etc. The error message is also different every time, e.g:</p>
  
  <pre><code>In depth(x$children[[length(x$children)]], ...) :
    reached elapsed time limit
  
  In paste(names[seq_len(n - 1L)], collapse = .grid.pathSep) :
    reached elapsed time limit
  
  In lapply(X = X, FUN = FUN, ...) : reached elapsed time limit
  
  In x$vp : reached elapsed time limit
  </code></pre>
  
  <p>None of these errors appear to refer to any of my data. This is a pc with R and Rstudio freshly installed and my data files, which look like this:</p>

  <p>I'm a little confused about what this error means and how to fix it, and I don't really understand the other answers when I have googled this error. </p>
