Problem with strptime generating missing values where none appear to exist
Dear R Helpers,
I am having difficulty with strptime. I wish to find the differences between
two vectors of times. I have apparently no difficulty to convert the vectors
to the appropriate format using strptime. But, then difftime does not
calculate all the differences.
Here is the code and output:-
dob=strptime(as.character(datx$BDT),'%d-%b-%y'); dob$year=dob$year-100

package zoo, function na.spline with option maxgap -> Error: attempt to apply non-function?
Hello,
I'm trying to use na.spline (package zoo) to fill some missing data in a time series.
this works fine, however, if I apply the 'maxgap' argument, I always get the error:
<------
Error in na.spline.vec(x., coredata(object.), xout = xout., ...) : attempt to apply non-function
------>
I couldn't find a similar error for this case in the mailing lists and zoo vignette,

Regression in strptime
This is definitely obscure but we had a unit test that called
.Internal(strptime, "1942/01/01", %Y/%m/%d") with timezone (TZ) set to
CET. In R-3.1.3 that returned "1942-01-01 CEST" which, paradoxically, is
correct as they evidently did strange things in Germany during the war
period. Java also returns the same. However, R-3.2.4 returns "1942-01-01
CET".

problem with data
Hello all!
I have a problem with my data in R. When I want to plot the following data,
I have a problem with y scale. The maximum value is cc. 10 degrees and in R
is about 100.
I use this code:
fasy<-read.table("gridd1.txt",sep="\t",dec=",",header=T,row.names=1)
# here are the years:
x <- as.numeric(rownames(fasy))
# extract a series that you want to plot:
y

OK, .Internal is not necessary to reproduce oddity in this area. I also see things like (notice 1980)

interpolation
Dear R-users,
I have a complex line by xy-values (ordered by z).
And I would like to get interpolated y-values on the positions of x = 0:600.
How do I get the correct points?

On the Use of the nnet Library
Dear List,
I am trying to solve a problem by the neural network method(library:
nnet). The problem is to express Weight in terms of Age , Sex and Height
for twenty people. The data frame consists of 20 observations with four
variables: Sex, Age, Height and Weight. Sex is treated as a factor, Age
and Weight are variables normalized to unity, as usual. I wanted to
construct a neural network, and so
