Looping multiple output values to dataframe
Dear R users,
I have various vector geometry operations to perform on 3-D coordinate data
located on multiple (500+) csv files. The code I have written for the
calculations works just fine. I have written a 'for' loop to automate the
task of extracting the coordinates from the files and perform the analyses.
The loop works reasonable well, but if the number of csv files is greater
than

system vs shell wait command
Dear All,
I try to invoke a second program (called "gencont") within a R script.
However this second program needs some time to finish. After finishing the
output should be read into R and used for further calculation.
Under windows, it perfectly works:
result<-shell("gencont < yn.txt",intern=TRUE,wait=TRUE)
# R waits untill the program finishes (apporx 3 min) and

how to find "p" in binomial(n,p)
I think the function you need is 'help.search'; try:
help.search("binomial")
and look for something obvious in the 'stats' package. A good deal quicker
and easier than posting to an internet forum!
Cheers, Mike.

Again, about boxplot
Thank you for your guys reply for my previous question. But I got one more
question about the boxplot. With the code in the R-help:
boxplot(len ~ dose, data = ToothGrowth,
boxwex = 0.25, at = 1:3 - 0.2,
subset = supp == "VC", col = "yellow",
main = "Guinea Pigs' Tooth Growth",
xlab = "Vitamin C dose mg",

About "Plot.new"
Hi, sorry for bothering your guys.
I will trying to make some nice graph using boxplot. when I check the help
file of boxplot, there is a sample code as:
boxplot(len ~ dose, data = ToothGrowth, add = TRUE,
boxwex = 0.25, at = 1:3 + 0.2,
subset = supp == "OJ", col = "orange")

Upper bands and lower bands
I explain better:
I have this percentage z<-1/(n*365) where n=20 so z is
0,000136986
Imagine: a matrix with length(n*365) so that
matrix result is
resultc(
1,
1-z
result previous row-z
result previous row-z
....
0)
If I plot this is a linear decreasing line
I want to plot an upper line wich is 10% higher tan resultc on the first
values and then decreasing so that last value will be 0.05.

outlier and whisker in boxplot
Hi, Dear R-users:
Sorry for bothering your guys again. I think I should rewrite my question.
I know how to extend whisker by using range. The question is that I will set
the range=1.5, and at the same time, I only want to show the extreme
outlier, like 0.01% and 99.99% percentile, so what should I do?
Thank you very much!

about the whisker in boxplot
Hi, Dear R-users,
I have a problem when I drawing a boxplot. I want to extend the whisker to
the 5% and the 95% quantiles and only show the most extreme outlier, like
0.01% and 99.99% percentiles. What should I do?
I saw something on boxplot.stat, but even I define the parameter in
boxplot.stat, what I should do next? how to connect it to boxplot?
Thank you very much!

help with simulate AR(1) data
Hi, sorry for bothering your guys again.
I want to simulate 100 AR(1) data with cor(x_t, x_t-1)=rho=0.3. The mean of
the first 70 data (x_1 to x_70) is 0 and the mean of the last 30 data (x_71
to x_100) is 2. Can I do it in the following way?
x <- arima.sim(list=(ar=0.3), 100)
mean <- c(rep(0, 70), rep(2, 30))
xnew <- x+mean
If the above code to simulate 100 AR(1) data is right, what

Dear all,
I have just sent an email with my problem, but I think no one can see the red part, beacuse it is black. So, i am writing again the codes:

Time series graphs, question about using zoo
Hi,
Can you tell me what is the meaning for "tail, 1" in "aggregate"?
I also want to get some similar graph, but the data is not time series data.
Suppose here is my data one, I want a graph with x-axis is just the
index(1:9).
The graph plot all the variable A, B,C,D. So there should be 4 lines for
each graph. For the A line, at each time point, the letter A should be on

about systemfit
Hello. I am still a newbie in R. Excuse me if I am asking something obvious. My efforts to get an answer through browsing the mailing archives failed. I want to perform an augmented Dickey-Fuller test and to obtain AIC and BIC and to be able to impose some linear restrictions on the ADF regression so as to decide the correct order of autoregression. However I could find no obvious way to impose

Upper bands and lower bands
Hi all
I want to add a band of fluctuaci?n (exponential decreading) to a linear
deacrecing values
Imagine: I have a matrix like c(10,9,8,7,6,5,4,3,2,1)
The thing is I want two new lines so that the m?ximum value of the new
colum on the m?ximum is from 10% to 5% higher and the same lower for the
m?nimum
the final two matix will be something like
c(10+0.10*10,9+0.089*9,8+0.075*8.....,1+0.05*1)

nomianl response model
Is there a way to estimate a nominal response model?
To be more specific let's say I want to calibrate:
\pi_{v}(\theta_j)=\frac{e^{\xi_{v}+\lambda_{v}\theta_j}}{\sum_{h=1}^m
e^{\xi_{h}+\lambda_{h}\theta_j}}
Where $\theta_j$ is a the dependent variable and I need to estimate
$\xi_{h}$ and $\lambda_{h}$ for $h \in {1...,m}$.
Thank you,
