how can i make my program faster
...each time when i want to add data into my data, i have to copy data of table into an array for each column, and then i add new data into my array, then i copy my array into the table one column by one column. For example
temptrial <- table1$trial;
temptrial <- c(temptrial, "1, 2");
tempx <- table1$x;
tempx <- c(tempx, "1, 2");
tempy <- table1$y;
tempy <- c(tempy, "1, 2");
table1 <- data.frame(trial = temptrial, x = tempx, y = tempy);
the way i am doing makes my program very slow, because i need to copy the data from one variable to another v...

series temporales. índices de variación estacional
...momento estoy viendo cosas muy simples, como descomponer una
serie en tendencia y componente estacional, usando la función decompose
y también la función stl.
Por ejemplo
# generamos 48 datos de una normal por ejemplo
x <- rnorm(48)
# creamos el objeto ts diciendo que los datos son mensuales
tempx <- ts(x,start=c(2008,1),frequency=12)
descomposicion1 <- decompose(tempx, type="mult")
# también se puede usar la función stl,
descomposicion2 <- stl(tx,s.window="periodic")
¿Puedo obtener los índices de variación estacional a partir de los
valores guardados en descom...

Odd behavior of plot function
Sorry, that's a cut and paste error. It should be either tempx or xtemp throughout.

Spider diagrams
Hi, I am trying to create what are called "spider diagrams" in the geochemical
literature using R. A spider diagram is basically a plot of the atomic number
versus the concentration on a log scale. Lines are drawn from each atomic
number for each sample.
Right now, my data frame looks like:
SAMPLE SITE V3 LA.NASC LAATNUM CE.NASC CEATMNUM

Odd behavior of plot function
The following code snippet taken from plot.survfit now gives me a surprising result:
tempx <- c(0, 400, 0, 0)
ytemp <- c(.0657, .98, 1, 0)
plot(range(xtemp), range(ytemp), log='y', type='n')
In that the max value for the x axis is now 10. The 0 on the end of ytemp was actually a
mistake and shouldn't be there, if you remove it then the upper limit is sensible...

plot survival points
Hi all,
I have a little problem.
I make an weibull survival analysis using the survival package. It,s OK, them
I have the functions. I plot this funcions with curve(). I want to make a
plot with the real survival points (proportion of alive x time) and them add
the curves to points. I have the time to dead, the censor data and my
trataments. To analysis the model is:
model1 <-
