Hi,

I've just started using R and RSPerl. I have some code as follows:

&R::initR("--no-save");

&R::call("t.test", (\@array1, \@array2));

t.test(c(0, 6.24280675278087, 6.35175793656943, 5.76925805661511, 7.0789316246711, 7.4636498661157, 8.13730810691084, 8.78203131644273, 9.64502765609435, 9.95631242346133, 5.83129579495516, 6.8798700754926, 7.31814159140937.......(REST OF THE ARRAY ELEMENTS)..... 4.91632461462501, 3.38099467434464, 3.91800507710569, 3.23867845216438, 3.38439026334577, 4.64918707140487, 3.23474917402449, 3.62966009445396, 3.36729582998647, 3.91999117507732))

Performed the call, result has length 9

My question is : with other functions such as sum and log10, the actual values of the result are displayed. Here the call seems to have worked but the output is not what you get when running t.test directly on the R command prompt..

data: data4[2] and data4[3]

t = 0.2186, df = 109.847, p-value = 0.8274
alternative hypothesis: true difference in means is not equal to 0
95 percent confidence interval:

-3722.830 4645.723

sample estimates:

mean of x mean of y

6185.139 5723.693

Thank you very much for the help!!

Sincerely,
