finding and describing missing data runs in a time series
...39;s start and their length. The closest thing I can use that I know about is timePlot in the openair package with statistic="frequency" but it only gives monthly summary data, and does not tell me if the missing data are clumped together or are dispersed.

ggplot2 - regression statistics how to display on plot
...Here is a sample script of what I am trying to accomplish:

df$x<-rnorm(100)
df$y<-rnorm(100)
df<-data.frame(df)
ggplot(df, aes(x=x,y=y))+geom_point()+geom_smooth(method=lm)
# would like to be able to showr squared and slope/intercept of lm

Chemical Names in Data Frames
...quot;])
I was wondering if there was a function to automatically convert these chemical names (with all sorts of numbers and minuses in the beginning) to something openair can handle? Or am I going to be stuck recoding several hundred chemical names in my database?

Chebyshev Inequality — MVUE
...Search and can not seem to find a function that will give me g_n or the MVUE for mean and variance of lognormal distribution.
Is there an R function that will give me g_n or will calculate an MVUE for the population mean and variance for the lognormal distribution?

how to handle missing values
This group impresses me, so far I have been helped with all my questions
within 24 hours. Thanks.
Therefore another one.
I am used to programs (such as STATA) where observations with missing values
that are included in a model are simply ignored in the analysis. So far I
have not been able to figure out how to deal with missing values in R and
have solved the problem by deleting observations

latex, Hmisc with MikTeX 2.8 produced "n&missing&unique" output
...recognize the style "{tabular}"? The only other symptom is that the output of the latex command hangs until I open the dvi output manually in my temp folder.
I have the geometry.sty and the ctable.sty loaded per the documentation in Hmisc... any ideas?

Read many cvs files
Hello R helpers,
I would like to automate this code for many files of the same type. But I
don´t know how to make it. In particular, i don´t know how to read many
files each one as an r object with the name of the file. Then a for loop
would be sufficient, right?
Many thanks and a happy new year.
Dominic

Subsetting to unique values
I want to take the first row of each unique ID value from a data frame.
For instance
> ddTable <-
data.frame(Id=c(1,1,2,2),name=c("Paul","Joe","Bob","Larry"))
I want a dataset that is
Id Name
1 Paul
2 Bob
> unique(ddTable)
Will give me all 4 rows, and
> unique(ddTable$Id)
Will give me c(1,2), but not accompanied by the name column.

Install R on Mac OS.X
I am running R 1.8.1 flawlessly on my mac with OS.X.3
My friend is running 1.6.1 but it is impossible for him to make 1.8.1
work. I do not understand why it should work better in my computer. I
do, however, have X.11 installed, he doesnt, could that be an issue and
if it is, does it suffice to install X.11 after RAqua has been
installed?
