finite mixture model (2-component gaussian): plotting component gaussian components?
Dear Knowledgeable R Community Members,
Please excuse my ignorance, I apologize in advance if this is an easy question, but I am a bit stumped and could use a little guidance.
I have a finite mixture modeling problem -- for example, a 2-component gaussian mixture -- where the components have a large overlap, and
I am trying to use the "mclust" package to solve this problem.

Omitting members of a sequence
Hello, this is just a point of curiosity with me. I want a sequence of
numbers from 64 to 70, omitting the 2nd and 4th numbers. I can do it
these ways:
> seq(64, 70)[-c(2, 4)]
[1] 64 66 68 69 70
> foo <- 64:70
> foo[-c(2, 4)]
[1] 64 66 68 69 70
But how come this doesn't work?
> 64:70[-c(2, 4)]
[1] 64 65 66 67 68 69 70
Just wondering.

Assignment working differently inside ifelse()
Hello all, I need to extract rows and columns from a data frame and put
them in a matrix. In some cases, there are no rows in the data frame
meeting the selection criteria. For those rows I want to put a row of
0's in the matrix. Here's my clumsy code:

Order of terms in formula changes aov() results

I know this is wrong, but why?
My mind has become corrupted by having to use SAS too much. I wanted to
calculate the difference of elements of two vectors if the signs are the
same. I tried it the corrupted way first:

imprv1 <- effects0[,3] - effects1[,3]
} else if (effects1[,3] > 0 & effects0[,3] > 0) {

[Bridge] Problem loading bridge.o

Conditionally constructing columns in a data frame
Hello, I have to construct 5 new columns in a data frame depending on
the value of another of the columns in the data frame. The only way I
could figure out to do this was to subset the data frame five times, do
the variable construction, and then rbind the subsets back together.
Here's part of the code I used:

[semi-OT] Using fortune() in an email signature
Hello, As you can see from my signature in this message, I use the R
fortune function to generate a fortune, which is then fed to the
signature program, which constructs a named pipe containing the
fortune-bearing sig, which is then included in mail messages. The
problem is that it's got extraneous junk in it and I can't figure out
how to get rid of it. This is the command that generates

How to shade area between lines in ggplot2
Hello,
I am running SVM and showing the results with ggplot2. The results
include the decision boundaries, which are two dashed lines parallel
to a solid line. I would like to remove the dashed lines and use a
shaded area instead. How can I do that?
Here is the code I wrote..

Cumulative Frequency Graph
Hi,
I am trying to create a Cumulative Frequency graph and I am using the
following example:
http://www.r-tutor.com/elementary-statistics/quantitative-data/cumulative-frequency-graph
When I plot this data, how do I put in "real values" on the x-axis, rather
than the values that
are used for the breaks
Thanks
