Hi Tim,
there are a couple of problems in your example.
(1) The most important is that your 'x' values for the matplot
are 1:5 (that is row numbers of your mat1 matrix)
and are seq(20,100,20) (that is, your vect vector) for your error bars.
Error bars are thus plotted outside the plotting

Ahem. Equivalent, my tired foot...

Hi,
I'm trying to figure out how to have R estimate partial derivatives for
logit models. As an example, I'm providing a (fake) scored observation in a
MNL with 3 categories of Y and 2 predictors (x01 and x02), and show the
right way to calculate it, but am looking for how to use an R function,
Ahem. Equivalent, my tired foot...
My bad, I wasn't paying attention.
May I suggest consulting a textbook *before* flunking ANOVA 101 ?
Harsh but warranted given my carelessness.

Hi,
I think this question is best explained using the following
self-contained toy example:
## cut code here and paste to R window
z - cbind(rep(c(BIC, hist), each = 150), rep(rep(c(5, 10, 30),
each = 50),2))
z - as.data.frame(z)
z - cbind(z, runif(300))
names(z) - c(Method, sigma, Error)
I don't know of anything that does the automated process like the example
software you link to, but here is one procedure that you can use to do it by
hand.
1. Brind the graph into R and plot it (as an image) using rimage or EBImage (or
other) packages.
2. use the locator function to find the
Now that we know what egen is, the answers are one-liners in R:
# Make up some data
vasdat - matrix ( sample ( 1:100, 3000, replace = TRUE ), ncol = 3 )
# Use apply for each ( MARGIN = 1 means rows, 2 means columns )
anycountresult - apply ( vasdat, MARGIN = 1, FUN = function ( x ) sum ( x %in%
See, we just jave different expectations of what is to be seen in the
help system, and are used to different formats. Yes, Stata thinks of
data as a rectangular array (although it stores it in memory, unlike
SAS). The inputs to -egen-, as well as the values produced, depend on
the particular
Try:
z - cbind(rep(c(BIC, hist), each = 150), rep(rep(c(5, 10, 30),
each = 50),2))
z - as.data.frame(z)
z - cbind(z, runif(300))

z$sigma - factor(z$sigma, c(5, 10, 30))
