Hi
Maybe I am missing something but in package "zoo" is function "na.locf", which
fills empty cells with previous value.
So when you read your file
dat<-read.table("", na="")
you can use
library(zoo)
sapply(dat, na.locf)
the only problem is that it changes factors to numeric representati

You appear to either be ignorant of the structure pf data frames or
have not expressed yourself clearly enough (for me, anyway). Please go
through a tutorial to learn about the fixed structure of data frames,
for which your request does not appear to reflect an understanding.

You really really need to go through one of the many R (web) tutorials
where this is discussed in detail. Or see the Intro to R tutorial that
ships with R. This is not the proper venue for learning how R handles
linear models and how its formula interface works. A terse treatment
can be found in ?l

Hello Everyone,
I have a data frame which looks something like this:
V1 <-c(1,2,3)
V2 <-c(5,6,7)
V3 <-c(9,10,11)
df <- data.frame(V1,V2,V3)
I want to add couple of text files at the beginning of df and save
the df as a csv file.
The csv file should look something like this:
Hi there,
I have a experimental design related question. I have done a experiment
with 3 factors. The design matrix is similar to:
data.frame(Factor.1 = rep(rep(0:2, each = 3),3), Factor.2 =
rep(c("U","S","N"), 9), Factor.3 = rep(0:2, each = 9))
Factor.1 Factor.2 Factor.3

Hi Rabby,
Before you run your regression, try this:
is.factor(Final$Cor)
If this returns TRUE, then this variable is a factor and it will be
treated as a number of levels rather than a set of numeric values.
This usually happens when a text file is read in and there is at least
one value that can
I can't think of a more appropriate time to point out that there is an
r-sig-debian mailing list that focuses on operating-system-related issues like

That's the kind of help that we like to provide. And for extra marks, you
can write a small function that will deal with consecutive NA values.

Hi everybody,
My name is Jackson and come here ask for a help to organize data.
I really need help from you. I have several data sets to organize.
I have to summarize precipitation data collected in different days and
months in only one table.
However, those data are disperse in days and times. T
Hi all,I had a question last week on asking for a function that will help me
draw three different circles on x,y,z axis based on polar coordinates (Each
X,Y,Z circle are coming from three independent measurements of 1-360 polar
coordinates). It turned out that there is no such function in R and
I forgot to mention that a circle with radius 0.05 cannot go from
(0,0.6) to (0,0.1), that's why I've changed the radius to 0.25, half the
distance between those points. I also chose the center point.

Hi Rabby,
It looks to me as though your variable Final$Cor is being treated as a
factor rather than a numeric value. This may be due to one or more
non-numeric values occurring in the data that is read in. Also you do
not have to use the Final$* notation in the formula as you have
specified the dat
Hi Chris,
You may know about the *apply family of functions. These slice various
data structures and "apply" a specified function to each slice,
usually returning a list of return values. As far as I am aware, you
can't access adjacent rows unless you reformat the data structure.
There is a way to
