...I'm doing wrong? Here's an example where I compare the first two ventilations with pairwise.t.test and t.test > pairwise.t.test(folate, ventilation, p.adj="none", pool.sd=F)         Pairwise comparisons using t tests with non-pooled SD data:  folate and ventilation           N2O+O2,24h N2O+O2,op N2O+O2,op 0.029      -        O2,24h    0.161      0.298    P value adjustment method: none > t.test(folate[1:8], folate[9:17], var.equal=F)         Welch Two Sample t-test data:  folate[1:8] and folate[9:17] t = 2.4901, df = 11.579, p-value = 0.02906 alternative hypothesis...

...I am experiencing difficulty in trying to generate a subscript '2' in an axis label. Although I can get the '2' into a subscript using expression(), R then forces me to leave at least one space between the '2' and the following character. My label is supposed to read 'N2O concentration (ppm)', and the space between the '2' and the 'O' makes it look rather inelegant! My code is the following (the comments in it are there to stop me forgetting what I have done, I am new to R): postscript(file="/Users/patrickmartin/Documents/York Innova Pr...

I am going to attempt to develop a wrapper for the R.dll library in the .Net framework. I successfully interfaced with some very simple functions from the library, but nothing close to do some data analysis. I dumped all the "publicly" available functions and attributes from the windows dll and found there are 2671 functions and attributes. I created an API document that
