Hi R users,
I am wondering if it there is R's function that can help integrate venn
diagram and pie chart to compare two related datasets.
I know the package limma has something built-in for making venn diagram, but
I guess it would be very painful to use line and text to specify the
Hi R users,
I am trying generate the indices for locating a in the string it come from.
Given the length of the string, it will take too long using the combn() for
further comparison. I am wondering if R has any built-in function for this
purpose.
To make it concrete:
this.substring=cc
Hi R users,
I am using built-in functions in igraph package to draw networks . I need
to compare several network with exactly the same structure but with edge
hightlighted differently. I am wondering if there is a way to save the
layout so that every graph will look the same as each other
Dear R users,
I am trying to draw a network using igraph package. I intend to place the
hub nodes (the ones with the relatively more connection with other nodes) in
the center of the graph. Also, the graph need to be in the fashion that the
higher the correlation between two nodes is , the
nodes. You mean
that the graph is weighted?
If you have a small graph, then you can refine the layout
interactively by using 'tkplot'.

Hi all,
I am coding for finding the root of f(x)= phi(x) -alpha where phi(x) is the
cumulative density function and alpha is constant . The problem right now is
I can't get the initialX representing the root out of the while loop when

Hey everyone,
The code I wrote executes correctly but is stalled seriously. Is there a
way to hasten execution without coming up with a brand new algorithm

Hey All,
I am wondering if there is a built-in function allowing us to locate a
particular word in a character vector.
ex: vector a

[7] spiderman
Is there any built-in function that can show superman are the first,
fourth and
