lines

I have a plot in polar coordinates. I used geom_path to connect the points, but I'd like the paths to be straight lines. Here's what I have so far: example <- data.frame(c(5,4,3),c(0.9,1.1,0.6)) colnames(example) <- c("r", "theta") myplot <- ggplot(example, aes(r, theta)) + geom_point(size=3.5) + coord_polar(theta="y", start = 3/2*pi, direction=-1) + scale_x_continuous(breaks=seq(0,max(example$r)), lim=c(0, max(example$r))) + scale_y_continuous(breaks=round(seq(0, 2*pi, by=pi/4),2), expand=c(0,0), lim=c(0,2*pi)) + geom_text(aes(label=rownames(example)), size=4.4, hjust=0.5, vjust=-1) + geom

I'm working with a very big text file (755Mb). I need to sort the lines (about 1890000) and then write them back in another file. I already noticed that discussion that has a starting file really similar to mine: Sorting Lines Based on words in them as keys The problem is that i cannot store the lines in a collection in memory because I get a Java Heap Space Exception (even if i expanded it at maximum)..(already tried!) I can't either open it with excel and use the sorting feature because the file is too large and it cannot be completely loaded.. I thought about using a DB ..but i think that

Is there a way to create a Three.js 3D line series with width and thickness? Even though the Three.js line object supports linewidth, this attribute is not yet supported in all browsers on all platforms in WebGL. Here's where you set linewidth in Three.js: var material = new THREE.LineBasicMaterial({ color: 0xff0000, linewidth: 5 }); The Three.js ribbon object - which had width - has recently been dropped. The Three.js tube object generates 3D extrusions but - being Bezier-based - the lines do not pass through the control points. Can anybody think of a method of drawing a line series

In Bash, how do I count the number of non-blank lines of code in a project? cat foo.c | sed '/^\s*$/d' | wc -l And if you consider comments blank lines: cat foo.pl | sed '/^\s*#/d;/^\s*$/d' | wc -l Although, that's language dependent. #!/bin/bash find . -path './pma' -prune -o -path './blog' -prune -o -path './punbb' -prune -o -path './js/3rdparty' -prune -o -print | egrep '\.php|\.as|\.sql|\.css|\.js' | grep -v '\.svn' | xargs cat | sed '/^\s*$/d' | wc -l The above will give you the total count of lines of code (blank lines removed) for a project (current folder and all subfolders recursively

I have a program which reads a text file and processes it to be seperated into sections. So the question is how can the program be changed to allow the program to skip reading the first 5 lines of the file while using the Stream Reader to read the file? Could someones please advise on the codes? Thanks! The Codes: class Program { static void Main(string[] args) { TextReader tr = new StreamReader(@"C:\Test\new.txt"); String SplitBy = "----------------------------------------"; // Skip first 5 lines of the text file? String fullLog = tr.ReadToEnd(); String[] sections = fullLog.Split(new string[]

Need some compact code for counting the number of lines in a string in Java. The string is to be separated by \r or \n . Each instance of those newline characters will be considered as a separate line. For example - "Hello\nWorld\nThis\nIs\t" should return 4. The prototype is private static int countLines(String str) {...} Can someone provide a compact set of statements? I have a solution at here but it is too long, I think. Thank you. private static int countLines(String str){ String[] lines = str.split("\r\n|\r|\n"); return lines.length; } How about this: String yourInput = "..."; Matcher m
