Re: [R] Visualizing a graph in the coordinate system given by x using vanila R

Hi Ante, As this is a homework problem, you will probably get a number of negative replies. You might want to look at the color.scale.lines function in the plotrix package. Perhaps you will find some clues in the code. Jim On Mon, May 8, 2017 at 9:22 AM, Ante Dilber wrote: > So I have the follow

[R] Visualizing a graph in the coordinate system given by x using vanila R

So I have the following problem, I need to write a function plotGraph(x , y) in R with the following properties: The argument x may be a matrix or data frame with two columns containing coordinates of vertices of a graph. The argument y must be a quadratic adjacency matrix that has as many rows an

Re: [R] Mac-specific encoding bug

Interesting! The odd thing is it works perfectly well on Linux platforms, at least - I guess it must be something to do with the Mac locales. Thanks! On Sun, May 7, 2017 at 1:51 PM, peter dalgaard wrote: > >> On 7 May 2017, at 08:36 , Oliver Keyes wrote: >> >> Hey all, >> >> I've ran into a weir

[R] visualization of KNN results in text classification

Hi all, Does anyone know what is the best way to visualize KNN(K nearest neighbor) results for classification of texts in R? My data set has only speeches and the type of the people for them which is control group or Alzheimer group, KNN classifies these two groups for me but I don't know how

[R] Mac-specific encoding bug

Hey all, I've ran into a weird quirk on Mac platforms, which you can read fully at https://github.com/Ironholds/urltools/issues/70 The long and the short of it is that one specific codepoint - \u04cf - does not print in a UTF-8-y way by default, except when run through cat(). Compare, for example
