Hi,   I am trying to compare two values using "==" operand, please take a look of the following example (I copied ALL what I did here without deleting any line)   >    bb<-1 > cc<-50 > cc==abs(bb+52) [1] FALSE > C<-53 > C<-53 > c<-53 > cc==abs(bb+52) [1] FALSE              I am expecting to see a TRUE here. Then I tried another way,   > abs(1+52)

...lls in the same spot as the previous version. Does anyone have any hints on how to make this if else statement work to do what I need? This is my first time trying to use these statements, and the S-plus manual i have is proving to be terribly unhelpful. What am I doing wrong? Mike Michael Rennie M.Sc.

...t; We get the same answer. The reason I figured this out is because I did this analysis first in SAS, and then tried to reproduce it in R. It must be something to do with my syntax, I imagine, but I can't see what it is. Any help anyone has would be greatly appreciated. Sincerely, Mike Rennie M.Sc.

...rting of data frames have to do with sorting by particular variables, not by the row names (which are just typically 1:n, and is rarely informative).

...ghts on how I can replicate the error? As far as I can tell, the only difference between the case where I am getting errors and the example above is that the levels of x1 in my case are words (i.e., "Smelly", "Howdy"), but strings are strings, aren't they?

Hi all, In the last couple of months, there have been two proposed patches for the regain play analysis code. The first by Nathan Rennie-Waldock: http://lists.xiph.org/pipermail/flac-dev/2011-December/003070.html simply adds some more higher sample rates. The second by Earl Chew: http://lists.xiph.org/pipermail/flac-dev/2012-January/003067.html is more comprehensive. Neither of the patches currently apply to the code th...

...don't say it, are greatly thankful for what you do here. Not only are you providing a service to people who are learning R, but indeed helping increase "R literacy".

...~x1*x2)) a.an$F This will return a vector of the F-values in order of the terms of the model. However, a similar application using Manova(): m.an<-Manova(lm(Y~x1~x2)) m.an$F Returns NULL. So does any attempt at calling the headers in the MANOVA table. Any thoughts? Mike -- -- Michael D. Rennie Ph.D. Candidate University of Toronto at Mississauga 3359 Missisagua Rd. N.

...have lost everything I once has associated with "vecs", and it's turned my actual values into arbitrary groupings. I assume this has something to do with the behaviour of factors?

Hi, My question is how do I gain control over what values the X and Y axis show. Below is a sample plot I have made and want the X axis to represent a time vector with values taking the form Q1.60, Q2.60, Q3.60...Q1.90..etc...Currently the X axis starts with value 0 and increases by 1 through the end of the sample. win.graph() matplot(v.0,log.diff.v.6,type="l",lty=1, col=2,

Is there any way to keep R from rounding your numbers, or to specify the # of decimal places you want for an element? -- Michael Rennie M.Sc.

...oes anyone know a way to extract JUST the t-statistics from the t.test, without the "t" character header, so I can generate a nice little vector? Alternatively, can I manipulate the output I am currently getting for the t- statistics so that I can isolate just the numbers? -- Michael Rennie Ph.D. Candidate University of Toronto at Mississauga 3359 Mississauga Rd.

...feel like my best opportunity is after the first line into the function, where I ask for the ANOVA table. Since this is a 2 X 5 table, presumably I should be able to evaluate it against the size of that table? Any thoughts on how to check that? I welcome any suggestions.
