Several lattice plots on one page
Dear all,
I am trying (!!!) to generate pdfs that have 8 plots on one page:
df = data.frame(
day = c(1,2,3,4),
var1 = c(1,2,3,4),
var2 = c(100,200,300,4000),
var3 = c(10,20,300,40000),
var4 = c(100000,20000,30000,4000),
var5 = c(10,20,30,40),
var6 = c(0.001,0.002,0.003,0.004),

splitting into multiple dataframes and then create a loop to work
Dear All
Sorry for this simple question, I could not solve it by spending days.
My data looks like this:

set.seed(1234)
clvar <- c( rep(1, 10), rep(2, 10), rep(3, 10), rep(4, 10)) # I have 100
level for this factor var;
yvar <- rnorm(40, 10,6);
var1 <- rnorm(40, 10,4); var2 <- rnorm(40, 10,4); var3 <- rnorm(40, 5, 2);
var4 <- rnorm(40, 10, 3); var5 <- rnorm(40, 15,

About multiple panels with limited space in-between
Hi R users,
I have a question about plotting. The following two datasets are an
example. What I have in mind is like the attached figure, but just have two
rows, top row is for DF1, bottom row is for DF2. The top and bottom rows,
have x-axis as var1, var2, var3, etc, while the y-axis represents A. For
each row, only the leftmost panel has y-axis ticks and label. For the two
rows, only the bottom

Bug in colnames of data.frames?
Hi,
I am using R 1.9.1 on on i686 PC with SuSE Linux 9.0.
I have a data.frame, e.g.:
> myData <- data.frame( var1 = c( 1:4 ), var2 = c (5:8 ) )
If I add a new column by
> myData$var3 <- myData[ , "var1" ] + myData[ , "var2" ]
everything is fine, but if I omit the commas:
> myData$var4 <- myData[ "var1" ] + myData[ "var2" ]

Sum of a couple of variables of which a few have NA values
Dear everyone,
I have looked all over the internet but I cannot find a way to solve my problem.
In my data I want to sum a couple of variables. Some of these
variables have NA values, and when I add them together, the result is
NA
dat <- data.frame(
id = gl(5,1),
var1 = rnorm(5, 10),
var2 = rnorm(5, 7),
var3 = rnorm(5, 6),
var4 = rnorm(5, 3),
var5 = rnorm(5, 8)
)

Add columns of dataset

Some columns are missed, for example, here the fourth (var3), sixth(var5)
and seventh (var6) columns. I want to first determine which columns are
missed in a huge dataset and then add the missed

vertically concatenating data frames
Hi,
what is the recommended way to vertically concatenate 2 data frames with
the same column names but different number of rows?
My problem is something along these lines:
df1 <- data.frame(var1=var1,var2=var2,var3=var3) # nrow(df1)=1000
df2 <- data.frame(var1=var4,var2=var5,var3=var6) # nrow(df2)=2000
I tried df <- c(df1,df2), no success. stack does not seem to be
appropriate

How to sum values across multiple variables using a wildcard?
I have a dataframe called "data" with 5 records (in rows) each of
which has been scored on each of many variables (in columns).
Five of the variables are named var1, var2, var3, var4, var5 using
headers. The other variables are named using other conventions.
I can create a new variable called var6 with the value 15 for each
record with this code:
> var6=var1+var2+var3+var4+var5

I need help with translating these SAS codes into R with lme()? I have a

SAS codes are:
