    <p>I decided it was important for R users to be able to play hangman and made an R hangman game. The problem is I don't do many plots for general release and so I don't know how to provide the user with a plot that works independent of platform or gui.</p> <p>Here's where you can download the complete package that contains large word bank:</p> <pre><code>library(devtools); install_github("hangman", "trinker") </code></pre> <p>The function that plots looks like this (I made the word bank go away for reproducibility):</p> <pre><code>hangman &lt;- function() { #x1 &lt;- DICTIONARY[sample(1:nrow(DICTIONARY), 1), 1] x1 &lt;- "trapped" x &lt;- unlist(strsplit(x1, NULL)) len &lt;- length(x) x2 &lt;- rep("_", len) chance &lt;- 0 win1 &lt;- 0 win &lt;- win1/len wrong &lt;- character() right &lt;- character() print(x2, quote = FALSE) hang.plot &lt;- function(){ #plotting function plot.new() mtext("HANGMAN", col = "blue", cex=2) mtext(paste(x2, collapse = " "), side = 1, cex=1.5) mtext("wrong", side = 3, cex=1.5, adj = 0, padj = 5, col = "red") text(.015, .8, paste(wrong, collapse = "\n"), offset=.3, cex=1.5, adj=c(0,1)) mtext("correct", side = 3, cex=1.5, adj = 1, padj = 5, col = "red") text(.96, .8, paste(right, collapse = "\n"), offset=.3, cex=1.5, adj=c(0,1)) segments(.365, .77, .365, .83, lwd=2) segments(.365, .83, .625, .83, lwd=2) segments(.625, .83, .625, .25, lwd=2) segments(.57, .25, .675, .25, lwd=2) parts &lt;- seq_len(length(wrong)) if (identical(wrong, character(0))) { parts &lt;- 0 } if (1 %in% parts) { mtext("O", side = 1, cex=4, adj = .365, padj = -7.2) mtext("o o", side = 1, cex=1, adj = .3725, padj = -28.2) mtext("&lt;", side = 1, cex=1, adj = .373, padj = -27.6) mtext("__", side = 1, cex=1, adj = .373, padj = -27.2) } if (2 %in% parts) { mtext("I", side = 1, cex=4, adj = .375, padj = -6.25) mtext("I", side = 1, cex=4, adj = .375, padj = -5.5) mtext("I", side = 1, cex=4, adj = .375, padj = -4.75) } if (3 %in% parts) { segments(.37, .57, .45, .63, lwd=7) } if (4 %in% parts) { segments(.37, .57, .29, .63, lwd=7) } if (5 %in% parts) { segments(.37, .426, .43, .3, lwd=7) mtext("__", side = 1, cex = 1, adj = .373, padj = -27.2, col = "white") mtext("O", side = 1, cex = 1.25, adj = .373, padj = -21.5, col="red") } if (6 %in% parts) { segments(.37, .426, .31, .3, lwd = 7) mtext("o o", side = 1, cex = 1, adj = .3725, padj = -28.2, col="white") mtext("x x", side = 1, cex=1, adj = .3725, padj = -28.2) mtext("You Lose", side = 1, cex=8, padj = -3, col = "darkgreen") mtext(paste(x2, collapse = " "), side = 1, cex=1.6, col="white") mtext(paste(x2, collapse = " "), side = 1, cex=1.5, col="white") mtext(paste(x2, collapse = " "), side = 1, adj = .51, cex=1.6, col="white") mtext(paste(x, collapse = " "), side = 1, cex=1.5) } if (win1 == len) { mtext("WINNER!", side = 1, cex=8, padj = -3, col = "green") mtext("WINNER!", side = 1, cex=8, adj = .1, padj = -3.1, col = "darkgreen") } } #end of hang.plot guess &lt;- function(){#start of guess function cat("\n","Choose a letter:","\n") y &lt;- scan(n=1,what = character(0),quiet=T) if (y %in% c(right, wrong)) { stop(paste0("You've already guessed ", y)) } if (!y %in% letters) { stop(paste0(y, " is not a letter")) } if (y %in% x) { right &lt;&lt;- c(right, y) win1 &lt;&lt;- sum(win1, sum(x %in% y)) win &lt;&lt;- win1/len message(paste0("Correct!","\n")) } else { wrong &lt;&lt;- c(wrong, y) chance &lt;&lt;- length(wrong) message(paste0("The word does not contain ", y, "\n")) } x2[x %in% right] &lt;&lt;- x[x %in% right] print(x2, quote = FALSE) hang.plot() }#end of guess function hang.plot() while(all(win1 != len &amp; chance &lt; 6)){ try(guess()) } if (win == 1) { outcome &lt;- "\nCongratulations! You Win!\n" } else { outcome &lt;- paste("\nSorry. You loose. The word is:", x1, "\n") } cat(outcome) } </code></pre> <p>This looks great on RGUI (in windows) where I created it but the plot is misconfigured in RStudio. How can I make the code plot everything in a way that lines up/looks good independent of gui/platform (my friend bryangoodrich suggested grid as a possibility)?</p>

    1. COJust can't resist saying that's one of the oddest homonymic errors I've seen in a while :-)

    2. COOK, srsly, my guess is that RStudio is assuming different default spatial units for its graph window. Perhaps a couple calls to `par` specifying the axis and text size units will solve the problem?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
