Re: [R] case-insensitive ZIP
Uwe and Brian,
Thanks for your attention to this one.
We currently have the following array of atypical situations in our
corporate installation:
(1) Central install directory, where I neither have nor can reasonably
want Administrator priviledges;
(2) IT staff willing to maintain R officially but wants to leave
*contributed* packages to user groups if at all possible;
(3) Direct access from R

read.zoo question
I have comma delimited asci data with each row being in the format :
2006-01-24 02:41:24.00011,1.22930000,5,1.22950000,7
.

.
and i'm trying to use read.zoo ( which is similar to read.table ) to
read in the data. the data goes all the way out to milliseconds and i
can't figure out what to put for the format field. if i put nothing,
then read.zoo gets rid of the the whole time and

not understanding a do.call
I did a ?do.call but i don't think i understand it.
if a, b,c,d are numeric vectors then could someone explain the
difference between
do.call("cbind",list(a,b,c,d))
and cbind(a,b,c,d).
or point to an archive on it.
the return value of cbind is a matrix or dataframe depending on what is
sent in but i don't
understand wheen it would be useful to use do.call. i realize it

looking for a cleaner way to do something
I have two numeric vectors each of length 17 and each is named the exact
same way.
so

temp1 is 1417 52 63 85

temp2 is 1213 41 50 97

hit return key before next gaph appears
i am looping and creating plots which are coming to the screen. i am in
linux and remember ( in a previopus life ) i used to use a command so
that the next graph n + 1 didn't appear on the screen until
i hit the return key after graph n appeared. i thought i remeber using
the command unix but when i type unix at the r prompt, it gices me
system. it's probably a deprecated
command then but

update on my weird problem
as jim pointed out ( i think we were figuring this out simultaneously.
thanks a lot jim ), it looks it does have something to do with the
fact that it's a zoo object because below i consider two cases.
in the first case, fxdatab is a zoo object and i get the length of temp
to be 1.
in the second case, fxdatac is a matrix and the results in temp are
correct.

avoiding a loop
I think I asked a similar question 3 years ago to the Splus list and I
think the answer was no or noone answered so noone should spend more
than 5 minutes on this
because it could definitely be a waste of time.
My question is whether the function below can be rewritten without a for
loop. apply is fine if it can be done that way but i doubt it. I call it
a lot and would
prefer to not loop.

did my searching but still couldn't find anything for bayesian dlm
I familarized myelf with kalmanlike and structts which are approaches
for building and estimating ( and forecasting ) state space models ( or
the equivalent arima models ).
back in 2003, gavin simpson wrote an email describing the west and
harrison apprach to estimate state space models and asked if anything
was out there for
using that approach. the goals of this approach are the same as kalman

trying to rotate barplot labels
hi everyone : i'm trying to rotate the x axis labels in my barlot ( yes,
since yesterday ) and my prob12matrix is 2 rows and 16 columns and i
followed the instructions in the
archive "rotate barplot labels". i was really looking forward to seeing
my labels turned but the plot just came back with no labels ? can anyone
see what might be going on ?

Use predict.lm
Hi All,
I created a two variable lm() model
slm<-lm(y[1:3000,8]~y[1:3000,12]+y[1:3000,15])
I made two predictions
predict(slm,newdata=y[201:3200,])
predict(slm,newdata=y[601:3600,])
there is no error message for either of these.
the results are identical, and identical to slm$fitted as well.
if this is not the right way to apply the model coefficients to a new
set of inputs, what is

plotting question
i have the following code below and at the end there are some plotting
statements.
it actualy looks quite nice when you run it but there is just one
strange thing happening that
don't know how to fix.
the three things being plotted are
aggfxdata[,logbidask] which has its own set of times ( it's a zoo object
).
rollmeanlogbidask which has a subset of the times that aggfxdata has.

extract certain values from a ts
Hi,
Having several daily wind speed time series I want to extract those
consecutive days over and below certain values (i.e. 5 < x <8) Don't

Thanks in advance

as.zoo question
this is probably a question for gabor or achim but maybe someone else
can answer it in case they are not around ?
Ifr you paste the code below ( again you would need the zoo and chron
libraries to be installed ),
you should get the error
"Error in Ops.POSIXt(frequency, freq) : %% not defined for "POSIXt"
objects".
What I want to do is take the numeric vector, lt, and

labelling of horizontal axis in acf function
this one is not a false alarm like my previous message.
i have cut and paste the code below so if anyone could run it would be
appreciated. basically,
my question is why the horizontal axis of the acf plot is labelled with
such huge numbers when
the labels should be 1 through 10 since may lag.max = 10 ?
i looked at the cdoe of acf but it was pretty much beyond me. i think it

2 "linux/R environment" questions
I was working on windows xp for a while and now i am back to linux ( not
sure which kind but I can find out if that helps ) and i just have two
questions that are
really environment R questions rather than R code questions.
1) i use emacs ( or xemacs if need be ) and i vaguely being able to cut
a line or a region in an emacs window and then paste it at my R prompt
so that it ran. Could I be

Time series plot
I have some time series data like
01/02/1990 0.531 0.479
01/03/1990 0.510 0.522
01/06/1990 0.602 0.604
there is no weekends and holidays.
how do I graph them in a single plot that the x-axis is the dates and
the y-axis is the time series?
Thank you

barplot question
i'm doing a bar plot and there are 16 column variables. is there a way
to make the variable names go down instead of across when you do the
barplot ?
because the names are so long, the barplot just shows 3 names and leaves
the rest out. if i could rotate the names 90 degrees, it would probably
fit a lot more.
or maybe i can use space to make the horizontal width longer ? I looed
up ?barlot but

hypothesis testing
This was sent to me by someone on the R-list ( I don't know her ) but I
don't have time to look at this right now so I told her I would send
it to the R-list because she said it keeps getting bounced when she
sends it.

really strange problem - has to be logic but i can't find it
would someone be kind enough to paste the code below into an R session (
ir you
can paste it into a file and just source it ) and take a look at it ? I
must be doing something wrong but
i can't find it.
I start out with a zoo object that has 100 elements in it.
then, i only want to keep the rows in which the bid and the ask are both
grester than zero. ( maybe my logic is wrong there ? ).

Auxilliary args in gls
I am trying to fit a B-spline regression model with a corStruct using
gls. I am using bs() and specifying the knots myself. If I make the
knots data-dependent, this works but has undesirable side-effects. I
prefer to reference an auxilliary variable "knots" in my model formula.
It should not be part of the data frame, as it is a vector of a
different length. How can this be done?
