Hello R Help List,
I am an R novice and trying to use the ifelse function to create a new binary
variable based off of the responses of two other binary variables; NAs are
involved. I pulled it off almost successfully, but when I checked the counts
of my new variable for accuracy, I found that
The following, locf2(), does what you want using only base R functions:
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 <-

Thank you so much Jim. I forgot to state that i was hoping to get it
without loops if possible.
Thanks again,

Hi Ek,
As I may have mentioned previously, if you don't mind stepping through
the data frame row by row you can do it like this:
eedf<-read.table(text="nam,val
mandy,1
,2
John,3
,4
,5
,6
Zara,7
,8",sep=",",header=TRUE,stringsAsFactors=FALSE)
for(row in 1:nrow(eedf))
if(eedf$nam[row] == "")
eedf
Not sure about your questions but I use rhdf5 to read statistical daily
bins from remote sensing ocean colour products (L3bin)

Maybe it's simpler to point out that nonlinear EQUATIONS need n equations for n
unknowns.
4 only equals 2 through the looking glass.
Alternatively, maybe the OP wants to adjust the 2 parameters to best fit the 4
relationships, in which
case nlsr package function nlfb() would be appropriate. No
Santi,
In the second line of your function you have the following:
f <- numeric(length(x))
This sets the length of this numeric vector (i.e., "f") to the length of the
vector "x".
Later, inside the function you assign to values to 4 elements of the vector "f".
This assumes that "f" is at least
Hi All—
I was looking at a posting from June-17. I managed to solve it. However,
when I changed the example in the posting, my solution will work only once
at a time which was mentioned by Jim Lemon on his response to the original
posting. This means that my solution will have to be repeated as m
Dear all,
I am relatively new to R and have had some difficulty in understanding an error
i get when running a code to solve a system of non-linear equations, with four
equations and two variables.
This is my code:

I believe that https://mran.microsoft.com/packages contains daily snapshots
of CRAN and you can use the 'checkpoint' package to retrieve packages as
they were on any given day.

Hi,
I am performing meta-regression using linear mixed-effect model with the
lme() function that has two fixed effect variables;one as a log
transformed variable (x) and one as factor (y) variable, and two nested
random intercept terms.
I want to save the predicted values from that model and sh

Dear All,
It is a common problem to update R for distributors. My challenge is to
maintain R module files for a cluster, using easybuild.
My question is: Is there a way to derive a list of cran packages and
their version for a given version of R?
In case addressing the R-help list is addres
Please keep the mailing list copied in replies. Yes, apparently the map_data
function is in the ggplot2 package, not the maps package.
