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 |
| NCQ06 | 13 |

values only within
identifiers

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)
stopifnot(is.logical
The following is an example:
| Item_Identifier | Item_Weight |
| FDP10 | 19 |
| FDP10 | |
| DRI11 | 8.26 |
| DRI11 | |
| FDW12 | 8.315 |
| FDW12 | |
The following is the one that i want to be. That is, filling NA values from the
previous Non-NA values.
| Item_Identifier | Item_Weight |

You can see a description of the ´dist´class at the end of the function
Hello Alex,
Look at the help page for the dist function. You'll see it doesn't

value. The function is not really intended for spatial point distance
calculations,
Hello I have some strange output from R and I try to understand how R works.
Could you please help me with that?
temp <- rbind (c(10,1),c(99,98))
> temp
[,1] [,2]
[1,] 101
[2,] 99 98
> dist(temp)
1
2 131.6435
> sqrt(dist(temp))
1
2 11.47360
so far so good
Please help me with this i need to submit my thesis .

Hi R-community,
I have the code as follows,i Fitted model as follows
lbeer<-log(beer_monthly)
t<-seq(1956,1995.2,length=length(beer_monthly)) #beer_monthly contains 400+
entries
t2=t^2
beer_fit_parabola=lm(lbeer~t+t2)
Below is not working for me.
Please help me in preparing the new data set for t

now I am learining random forest and using random forest package, I can get
the OOB error rates, and test set rate, now I want to get the training set
error rate, how can I do?
pgp.rf<-randomForest(x.tr,y.tr,x.ts,y.ts,ntree=1e3,keep.forest=FALSE,do.trace=1e2)
using the code can get oob and t
