[R] Formatting a Table

I've created a short program to print a table of learning curve factors. However, I cannot figure out how to format the table to: 1) Get rid of the [1]s in the first column and replace it with the values of N. 2) Line up the first row with the factors (decimal fractions). Thanks for any help. The

[R] Wilcoxon nonparametric p-values

When I use wilcox.test, I get vastly different p-values than the problems from Statistics textbooks. For example: The following problem comes from "Applied Statistics and Probability for Engineers", 2nd Edition, by D. C. Montgomery. Page736, problem 14.7. The problem is to compare the sample dat

Re: [R] numeric format

Thanks, Erik, This is a partial copy of my code. I want to get rid of the left column of integers and I want to control the number of decimal places after the decimal point. > j<-0.4 > for(i in 1:20){ + j=j+0.1;cp[i]<-pnorm(-j*3)*10^6;ratio[i]<-j} > table<-data.frame(ratio,cp) > table rati

[R] numeric format

Hi! I'm an R newbie and this should be a trivial problem, but I can't make it work and cannot find what I'm doing wrong in the literature. I entered the the command: table<-data.frame(x, scientific=F, digits=4) table This prints a column of x with 16 useless decimal places after the decimal point.

[R] Plotting 3 vectors on one graph.

I'm an R newbie and am trying to plot 3 vectors, say a,b,c. I have downloaded 3 R manuals and searched your forum. There are plenty of X vs Y examples, but cannot find how to plot 3, or more vectors one one graph. I'm sure I overlooked something. Thanks for any help. CHV -- View this message i

[R] Loop with variable index

I have a list of 20 values. The first time through a loop I want to find the mean and stnd.dev. of the first two values; the second time through the loop I want to find the mean and stnd. dev. of the first 3 values, etc. until the last time through the loop I want to find the mean and stnd. dev.

[R] R loops

I'm a new user and am having trouble with loops. In the following, I'm trying to add the results of "test" and the loops are not working. I've simplified the loop. What am I doing wrong? Thanks! > test<-numeric(20) > tot<-numeric(20) > for(i in 1:20){test[i]<-1} > for (i in 1:20){tot[i]<-(test[i]
