Stacked density plots
Hello R-community,
I want to generate stacked density plots in lattice. My data consist of a numeric variable ('pid') that is measured in different individuals ('id'), which can be divided in two types ('type') and the measurements were repeated a different time points ('day').
I read in the Lattice book that this can be done using the 'flowViz'

R console closes on its own
Dear R-experts,
I am running a script that has the following
structure:
windows(height=5.5,width=8)
dat<-read.csv("myfile.csv")
names(dat)<-c('a','b','c','d')
dat<-dat[,1:4]
xyplot(dat$a~dat$b)
Then I usually save the plot as a PDF (from the
menu in the R console). I can save the PDF twice in a
row; but at the third time, right when I

Ordering the levels of a vector
Hi,
I have a vector in a data frame that looks
something like this:
day<-c('Day -1','Day 6','Day 10')
This vector specifies the order in which several
panel will appear in a lattice plots. But the order in
which such plots will appear will be the following:
Day -1, Day 10, Day 6. Which makes sense, but I cannot
name the Days like this: Day -01,Day 10, Day 06,

Removing Inf and Inf values from a fata frame
Hi,
I have a csv file with empty values, when I apply
the different functions (mean, std, etc.) I create a
new data frame, the empty values generate Inf and -Inf
values. How can I remove those Inf and -Inf values
from the new data frame? I already specified na.rm in
the mean and std functions, but the values are still
there.
Thank you,

Substitution of Variables
Hi,
I need to run a script under the variable (that
comes from a csv file) that is assigned to another
variable. This is very a simplified version of what I
want to do:
data<-read.csv('name.csv')
names(data)<-("VA","VB","VC")
v<-VA
mn(v)
Thank you in advance,

Multiple lines with a different color assigned to each line (corrected code)
Sorry, I just realized I didn't type in the correct
names of the variables I am working with, this is how
it should be:
plot(1,1,type="n")
for (i in summ$tx) {
points(summ$timep[summ$tx==i],summ$mn[summ$tx==i])
lines(summ$timep[summ$tx==i],summ$mn[summ$tx==i])
}
Thank you,

Reordering levels of a factor when the factor is part of a data frame
Hello R-users,
I have a data frame whose names of columns I don't know a priori, but the user of my code will know them. The user is supposed to save the name of the column that will need some reordering of the levels of the factor later on. The name of the column will be saved in an object called:
variab
the data frame is called df.

Replecing empty values with a letter (continuation)
Sorry, I hit the send botton by accident. Here is my
code so far:

dat[is.na(dat]<-'N'
But it doesn't replace the <NA> for the letter 'N'.
I am using R v 2/7/0, running it under Windows

Legend outside plotting area
Hi,
I have been trying many of the suggested options
to place a legend outside plotting area, including
something like this:
par(xpd=T,
oma=par()$oma+c(4.5,0,1.5,0),mar=par()$mar+c(1,0,1,0)
But the aspect of the four plots gets compromised
when I change the margin settings. I cannot use mtext
because I need to use colors for the text. I tried
layout, but wouldn't let me include

Dismiss previous email
Sorry about that, it was sent by accident.
I have a data frame that looks something like this:
id day k
56 -1 566
63 -1 680
73 -1 773
56 2 298
63 2 273
Of course, it is a very simplified version of the
real data frame I am working on. I need to add another
column that would represent a percent change in k from
day -1, by id. I put only two ids at day 2 to
