[R] Analyzing large files faster

I'm trying to analyze the following data set (sample): IDadj.P.Val logFCGene.symbol 1419156_at5.32e-12 2.6462565 Sox4 1433575_at5.32e-12 3.9417089 Sox4 1428942_at2.64e-11 3.9163618 Mt2 1454699_at2.69e-10

Re: [R] Why does the graph converge?

Well I didn't expect it to converge because the first three lines (black, orange and turquoise) didn't converge. I was trying to find a condition in which it would be more efficient for T cells to spend less time in the lymph nodes, and I did when you increase the number of DC's per lymph node

[R] Why does the graph converge?

I have a set of functions: Probability - function(N, f, w, b, l, n, q) { #N is the number of lymph nodes #f is the fraction of Dendritic cells (in the correct node) that have the antigen #w is time in terms of hours #b is the starting position (somewhere in the

Re: [R] An infinite recursion error please explain!

In response to the second question about the placement of D=t, there are two instances of it: once after the comment starts inside node (After the line with the comment start end in first node) and one after starts outside node. Did that answer the question? I don't know if this helps, but I

Re: [R] An infinite recursion error please explain!

edit: I fixed it; apparently I needed to change the ceiling(w/q) to w%/%q, though I'm not really sure why that made such a difference. -- View this message in context: http://r.789695.n4.nabble.com/An-infinite-recursion-error-please-explain-tp3688260p3689621.html Sent from the R help mailing

[R] An infinite recursion error please explain!

Probability - function(N, f, w, b, y, t, q) { #N is the number of lymph nodes #f is the fraction of Dendritic cells (in the correct node) that have the antigen #w is time in terms of hours #b is the starting position (somewhere in the node or somewhere in the gap

[R] Explain how it gets back out?

Probability - function(N, f, m, b, x, t) { #N is the number of lymph nodes #f is the fraction of Dendritic cells (in the correct node) that have the antigen #m is the number of time steps #b is the starting position (somewhere in the node or somewhere in the gap

[R] exponent function help??

I'm trying to make a function that will output the exponent... so f2(2,2) = 4 and f2(2,3)=8. But I don't want to just use the x^n function, I want to do it another way, and without a recursion. I did the follow code but for some reason it doesn't work. Help please? f2 - function(x, n) #without

[R] Summation resulting in a list?

Probability - function(N, f, m, b, x, t) { #N is the number of lymph nodes #f is the fraction of Dendritic cells (in the correct node) that have the antigen #m is the number of time steps #b is the starting position (somewhere in the node or somewhere in the gap

Re: [R] Summation resulting in a list?

Use the tapply() function as in tapply(b,m,sum) HTH, Daniel Don't b and m have to be the same length then? What if they're not? And would I just put the tapply() instead of everything else in my summing function? (Sorry! I'm kind of newbie at this -_-;) -- View this message in context:

Re: [R] user input.

try something like: cat(\n,Enter your number,\n) # prompt y-scan(n=1) #scans the line before ? perhaps? -- View this message in context: http://r.789695.n4.nabble.com/user-input-tp3660993p3661031.html Sent from the R help mailing list archive at Nabble.com.

[R] problems with ifelse??

I have the following code to determine the probability of a t-cell encountering an antigen after m steps. probability - function(N, f, m, b, x, t) { #using ifelse instead of if/else #N is the number of lymph nodes #f is the fraction of Dendritic cells (in the correct node) that
