Hello, I've come across a problem in developing a set of custom functions to calculate the number of hours of daylight at a given latitude, and the number of days a date precedes or secedes the summer solstice. I discovered an inconsistency concerning leap years between my derived values and those from the US naval databases. It seems as far as I can figure that my inconsistency arises either

Ok, Thanks foe the answer, Ken: *1L, 2L etc are integers. (That is, identical to as.integer(1) , as.integer(2) etc) Using integers (instead of "numeric" type) is more efficient as here they're used as indexes and would be converted to integer anyway. Compare > is(1) ... and > is(1L) 1L:p is the sequence 1, 2, 3, ..., p (just like 1:p) Just for curiosity, what is

Hello all, I've been using binconf (package Hmisc) at a range of alpha values and noticed that using the 'Wilson' method when alpha is larger (i.e. narrow CI), results in the upper value being smaller than the lower value. The 'exact' and 'asymptotic' methods give results in the realm I'd expect. But the help file suggests: "Following Agresti and Coull, the

Dear All, I am actually on R-devel using shell consol. When I run RStudio, it can't find libR.so in the new /lib folder where is libRblas.so libRlapack.so. At first step I configure R-devel to share library with ./configure --enable-R-shlib. when I copied libR.so from /usr/lib/R/lib/libR.so (stable version R 3.1) to /usr/local/R-devel/lib/libR.so (R-devel version), That doesn't work.

Dear R users, I'm using the "ineq" package to calculate the values ​​of Gini and Lorenz coefficients and to and plot Lorenz graph. I want to plot on the same diagram, curves from two different populations, that have different "n". How can I do this?   Best regards,   Patricia [[alternative HTML version deleted]]

I hope the subject says it all. I want to be able to use an lm object and the associated coefficients to create function that can produce "expected" "y" values given inputs. Thanks, KW -- [[alternative HTML version deleted]]

Hello, I've got a lattice plot and need to add text into the bottom margin of the plotting area (below the bottom legend). This seems to work in principle using grid.arrange, yet the text to be added is rather long. As a consequence, it gets clipped: require(lattice) require(grid) myplot <- xyplot(1~1) mytext <- textGrob("This is such a very very long text that it goes on forever
