Replace NaN with zero
I need help with replacing NaN with zero (the value '0') in my dataset.
The reason is that I can't get it to graph because of the NaN in the
dataset. I have tried:
data[is.nan(data)] <- 0
that others have suggested in the help archives but this does nothing so
I am not sure what I am doing wrong.
Thanks in advance for your help.

I am plotting this using barchart (there is probably something better
but it gives me the results I want) and I would like the x-axis to have
the names of the months instead of the month numbers. So I have

Formatted text output
How does one write formatted, say "C style", output to a text file. I want something like "y=mx+b" for my linear regressions but with m and b derived from the fit objects. Also, how does one go about extracting just the slope or intercept from such an object. - Greg

Sum of specific column
I have a data set that I have imported (not sure if that makes a
difference) and I would like to calculate the sum of only specific
columns. I have tried
>colSums(dataset, by=list(dataset$col5), dims=1) and I get an error of
unused arguments
I have also tried
>aggregate(dataset, by=list(dataset$col5), sum) and I get the error that
sum is not meaningful for factors.

Barplot by two variables
Hi all
I have a bit of a problem. I want to make a barplot of some data. My
data is of a score that is separated by year and by a limit (above 3 and
below 3 to calculate the score).
Year Limit HSS
1999 ALT 0.675
1999 VFR 0.521
2000 ALT 0.264
2000 VFR 0.295
I would like to have a barplot with year on the x axis and HSS on the y
axis and the two limits as two different colors to show the

How to group a count
Hello R users
I have a dataset that has different types of records with different
dates and times pertaining to each. I would like to have a bar graph of
a count of the types(ie. The number of types) of recods by hour grouped
by year. So the count of the types would be the y axis, the hour on the
x axis and then grouped by year for easy comparison. I think that I
have to use barchart however I

Barchart legend position
I am using barchart to make charts for some data with a lot more
functions and labels and such in the command.
barchart(Freq ~ factor(HH), data = dataset1, group= year)
So I have my data grouped by year and I get a legend at the top of
graph, which is great cause I need the legend for the different years
but it is a weird spot. So how can I manipulate the legend, ie. Move
it, shrink it, do

Subset any value and blanks
Hi everyone
I need help with subseting a data set. In my dataset there is a
specific row that will either have a value or be blank. I would like to
subset (or split) the dataset into one dataset with the row that has the
value and another dataset that has just the blanks. Now the thing is
that the row that has the value in it, the value is not always the same,
it is a time stamp of when

Assign name to a name
I would like to know how I can assign a name to a name. I have a
dataset that has different years in it. I am writing scripts using R
and I would like to give a month a generic name and then use the generic
name to do different analysis. The reason for the generic name would be
so that I only have to change one thing if I wanted to change the year.
For example.

map points from scatterplot3d onto 2d fitted plane
Dear R helpers,
I have a 3D scatter plot that I have generated from scatterplot3d (which
looks great- thanks!) and I can see that the points in my graph fall in a
plane.
Following the example 5 from 3D scatter plot (below) I have fitted a
regression plane.
Now what I would like to do is a rotation so that my new co-ordinate system
is about the fitted plane (by finding the normal to the plane

I'm kinda new, so i'm wondering how should i configure [homes] section, so
only two of many users (e.g. "user1" and "user2") could see it shared in

stability measures for heirarchical clustering
Dear R users,
I'm interested in measuring the stability of a heirarchical clustering, of
the overall clustering and finding sub clusters (from cutting the
heirarchical clustering at different levels) which demonstrate stability.
I saw some postings on the R help from a while back about bootstrapping for
clustering (using sample and generating a consesus tree with a web based
tool CONSENSE)

Help with creating date as POSIXct
Dear list,
I want to create a POSIX time vector as follows:
day <- as.character("110809")
time.t <- 1:3600
t.min <- time.t %/% 60
t.sec <- time.t-t.min*60
DATE <- as.POSIXct(strptime(paste(day,t.min,t.sec),"%y%m%d %M%S"))
Tail(DATE)
The problem is that the last element (3600) returns a NA and I don't
understand why. 600, 1200, 2400

Making a series of similar, but modified .r files - suggested method(s)?
Dear all:
Any suggestions are much appreciated. I am looking for a way to make a
series of similar, but slightly modified, .r files.
My issue is automating making 320 .r files that change the for(i in 1:x) in
my base .r file (as well as other elements, e.g., the load(...),
setwd(...)). For smaller jobs running on a single computer with batch files,
I have been manually changing the for(i in 1:x)
