Hi. Thanks for the function. My bad, after looking at the csv file, it seems
that NA values come not only from previous Non-NA values but also from the next
Non-NA values. Example:
| NCQ05 | 11.395 |
| NCQ05 | 11.395 |
| NCQ05 | |
| NCQ06 | |
| NCQ06 | 13 |

Hi
why nonumeric values in data identifier matters?
Some toy data
dat<-data.frame(ie=rep(letters[1:3], each=3), iw=rnorm(9))
dat[c(2, 4,6, 9),2]<-NA
library(zoo)
ave(dat$iw, dat$ie, FUN=function(x) na.locf(x, na.rm=FALSE))
You can use ave together with na.locf to propagate nonumeric values only
You could use the following function
locf2 <- function(x, initial=NA, IS_BAD = is.na) {
# Replace 'bad' values in 'x' with last previous non-bad value.
# If no previous non-bad value, replace with 'initial'.
stopifnot(is.function(IS_BAD))
good <- !IS_BAD(x)

The problem was that i had my csv file on the descop. It should have been in

Hello Alex,
Look at the help page for the dist function. You'll see it doesn't
return a simple vector or matrix, rather a "dist" class object which
is why you got a surprise when you tried to treat it like a simple

How important it is to
In R a function only returns the last evaluation, so you need to wrap
up all of the local results into a list at the end of the function.

You need to protect your matrix by I ()
Btw: I'm actually writing a package for handling spectra that I plan to
release in some weeks.
It contains a vignette showing how pls calibration can be done.

The bad news, as others have indicated, is that this list is not for
homework. The good news is that all of this is extremely easy in R!!!

Is this homework?
If so, please read the posting guide and note the part about homework.
Specifically, "Basic statistics and classroom homework: R-help is not
intended for these."

you are likely to get a bashing for asking people to do your homework for
you!

Hi to all...i'm
Do you mean how to create an R function, CD, that
represents the resulting function of x? If that's it
then try this:
> CD <- function(x) {}
> body(CD) <- yacas("Integrate(y,0,1-x)2 - x - y - 1")[[1]]
> CD
function (x)
(1 - x)^2 - (1 - x)^2/2
See ?bodyAsExpression for more info. Also try:
Is this homework? Anyway, the attachment has been stripped off. Here
is how to plot the function.
fun <- function(x, y){
a <- 4
b <- x^2
d <- y^2
z <- a-b-d
return(z)
}
a <- fun(seq(-1000,1000,1), seq(-1000,1000,1))
plot(a)
#integration s
For the first question, you have provided the answer --
try(nls(...)). Was there something else you wanted?
For part 2, this should work:
for (i in names(myData)[-1]){ # skip first column with "Time"
write.table(myData[, c("Time", i)], file=i)
}

There are a lot of syntax errors such as unclosed parentheses, missing commas
etc; Example: exp@(@lgamma((k+1)/2)-lgamma(k/2)*1/sqrt(k), where the
parenthesis between the @s is not closed. I suggest you get an editor such
as "Tinn" that can highlight those for you. In addition I notice that you

Hello again,
Sorry but the code that I insert wasn't write. Should be like this:
fit_2323v_168f<-auto.arima(regts.ts, d = NA, D = NA, max.p = 2, max.q = 2,
max.P = 1, max.Q = 1, max.order = 5,
start.p=0, start.q=0, start.P=0, start.Q=0,
