...) gives weird coefficients: > coefficients(f) (Intercept) poly(x, 2)1 poly(x, 2)2 4.6666667 5.6568542 0.8164966 However the fitted() result makes sense: > fitted(f) 1 2 3 1 4 9 This is very confusing. How should one understand the result of coefficients()?

...ux kernel. It hangs after printing the ip information row. No traffic is observed at this point on the network. The pxelinux is transferred to the client through a tftp server and with no problems. What options do I have to proceed from this point and try to find out where the problem is?

...quired tools for doing so? I have tried to perform linear fittings and to claim that the slope of the fitted line in (c) is more significant than the lines in (a), (b), and (d), but this does not seem convincing to me. Are there standard toolboxes for such cases? Thanks for any suggestions / tips, Firas. -------------- next part -------------- A non-text attachment was scrubbed...

I need loops to apply some functions on pairs (not necessarily successive) of rows in a dataframe. Thankful for any advices, Firas.

...e pxelinux starts executing. Now I am not sure how to proceed. I am also wondering if the instruction "int 16h" has such a far reaching effects. Could it be the reason for the failing checksum and the not responding keyboard (after all it managed to stuck my whole pc)? To be concluded.

...or: > bIm[,,1] [1] TRUE TRUE TRUE TRUE TRUE This causes a lot of trouble in the R code as one would have expected to get a 2D array but ends up with this "logical" vector. Is this the way it was meant to be? Does not this behavior bother anyone else besides me? Thanks for the help, Firas.

...time decreases to > system.time( calculateKMedian( a, 3)) [1] 14.821 0.005 14.829 0.000 0.000 But 14 seconds are still pretty expensive for just scanning the array. Is there anything I can do to speed the indexing and the sub-sectioning of the 3d array in this case? Thanks for the help, Firas.

...g such an interface could be very useful. Alternatively, ImageMagick has a couple of different interfaces (including to C and C++). I was wondering if one can use these to call ImageMagick functions from R. I am posting a similar question on the imagemagick mailing lists too. Thanks for the help, Firas.

...stion. I am confused about when to use the GAM package and when to use the MGCV package?? My Model is a GAM model of continuous outcome and many non-linear continuous predictors (using the "s" function) as well as categorical predictors. Thanks in advance for your help and time.

...I am not totally sure, this seems to remind me of the conditional expectation of Y given X - maybe it is called the conditional deviation?) Is their a built in procedure in R for calculating the above? Otherwise, what would be the easiest way to achieve it? (factors maybe?) Thankful for the help, Firas.

...t. This problem occur with paste, cat, and print (i.e. paste(100000)="1e+05" and so on). I tried to change the "digit" option in "options()" but that did not help. Is is possible to change the behavior of the coercing or are there any work arounds? Thanks in advance, Firas.

Hi R users, I'd like to draw a nomogram using a competing-risks regression (crr function in R), rather than a cox regression. However, the nomogram function provided in the Design package is not good for this purpose. Do you have any suggestion. I really appreciate your help Many thanks F.Abdollah, MD San-Raffele hospital Milan, Italy -- View this message in context:
