I cannot figure out how to draw a certain plot: could someone help me out?
I have this data.frame from a survey

simple intro to cluster analysis using R
I am looking for simple introduction to cluster analysis using R, that would
be understandable to a novice in statistics. Or, could someone perhaps help
me understand how to proceed in my analysis? I am very new to both statistics
and R, but am trying hard to avoid having to use SPSS as everyone around
me...

charset in graphics
How do I make Lithuanian characters display correctly in R graphics?
Instead of the special characters for Lithuanian language I get question
marks...
I use Ubuntu Feisty, the locale is utf-8 ...
Do I need to specify somewhere the locale for R, or - default font for the
graphics?

Question on survey package
Is there a way to use one of the functions in the survey package to get
a table of estimated percentages (or proportions) and the standard error
for each? For example, suppose that AGECODE AND SEX are two factors
with 5 and 2 levels.
The 5x2 AGECODE x SEX table would have the estimated percentage of
persons in each cell,
100*(sum of weights in the cell) / (sum of all weights)
and the std

svytable and na's
hi,
i am trying to work with the survey package in order to apply survey design weights. the data set i am using - ess - contains missing values.
my question: when using svytable(~variable1+variable2, design=my.svydesign.object, na.rm=T) the resulting crosstable contains all missings although i defined the na's as such.
any ideas???
thanks a lot,

Package survey
Hi,
I’m using the svyby for total statistics, for example:
svyby(~p_igov,~div_a,desenho_nps,svytotal,drop.empty.groups=TRUE,vartype
=c("se","var","cvpct"))
In the numerical variable p_igov (and others) I have many non responses
but if I maintain the NA it doesn’t work.

how to include 'NA's in xtabs?
Hello!
I have a dataset with NA's in some variables (factors), for example:
$ P67 : Factor w/ 2 levels "-","+": NA 2 1 NA NA 2 1 1 2 NA ...
I need to use 'xtabs' like
xtabs(~x$P67)
It works well and produces something like this:
x$P67
- +
779 1318
but i want to compute NA's too, like this:
x$P67
- + NA

t-test between percentages
Hi all,
though i know this is a simple question, i really hope someone could.
I am just trying to compare percents respectively the difference in
percents by a simple test. t.test usually compares means and is
working like it is supposed to be. Now i wonder how i can use a test
in R to test for significant difference between two percentages.

Haven't heard from you in a long time. Perhaps you want something like this:

Viewing certain numbers without NA's
Dear R Community,
We have recently installed R 1.5.0 on several workstations. Ever since,
if I try to extract certain numbers or lines from a file (which contains
many NA's), I don't only get my desired line but all other lines which
contain NA's. In a file with 15000 rows and 7500 NA's this is not very
practical. In the earlier R-Version this worked when I typed in the

Length of vector without NA's
Hi,
this following code:
x<-c(1,2,NA)
length(x)
returns 3, correctly counting numbers as well as NA's. How can I
exclude NA's from this count?

Apparent bug in summary.data.frame() with columns of Date class and NA's present
Hi all,
Based upon an exchange with G?ran Brostr?m on R-Help today:
https://stat.ethz.ch/pipermail/r-help/2016-February/435992.html
there appears to be a bug in summary.data.frame() in the case where a data frame contains Date class columns that contain NA's and other columns, if present, do not.
Example, modified from R-Help:
x <- c(18000000, 18810924, 19091227, 19027233, 19310526,

subsetting with NA's
Hi,
I often have large dataframes with many variables and many NA's, from which I
would like to subset out some rows. Here is a toy example:
> x <- data.frame(a = c("x", "y", "z"), b = c(1, NA, 5))
> x
a b
1 x 1
2 y NA
3 z 5
I realize that, if I know the values in x$b that I want to subset, things are easy:
> x[x$b %in% c(1),]
a b
1 x 1

Should NA's in summary() output always be reported???
Consider
> summary(1:5)
Min. 1st Qu. Median Mean 3rd Qu. Max.
1 2 3 3 4 5
> summary(c(1:5,NA))
Min. 1st Qu. Median Mean 3rd Qu. Max. NA's
1 2 3 3 4 5 1
Wouldn't it be more stringent if "NA's" was also reported in the first case??

Cross Tables with odfTable in odfweave

na.approx and columns with NA's
Hi,
I have a object 'zoo':

where some columns only have NA's values (representing land data in a

'na.approx' for individual columns from the zz matrix, but when applied
to the whole matrix:
