Hi Zuhri,
Try:
mydf<-mydf[,c(2,1)]

I have a problem regarding R. How can I move my 2nd column into 1st column.

Hi,
I typically start R with "--no-restore --no-save" (to avoid .RData
files being written) and would like to have the same behavior under 'R
CMD BATCH'. I use R_BATCH_OPTIONS="--no-restore --no-save" in my
~/.Renviron but running an R script with 'R CMD BATCH' still produces
a .RData file. What's
Hello,
I cannot reproduce the error but I coerce to class "Date" first.
MOSCFD50[[1]] <- as.Date(MOSCFD50[[1]])
names(MOSCFD50) <- c("date", "value")
# Your subset
Year <- subset(MOSCFD50, date > "1998-01-01" & date < "2005-12-31")
# Another way, if there are NA's, use which(i)
i <- MOSCFD50$
To get a quick answer to your question you should provide a smallexample
that one can simply copy and paste into an R session. It also helps to
show some details about how something does not work, more than " But it
didn't work." E.g.,
d <- read.table(header=FALSE, text="1997-11-23 -2.917096290
Dear Bert and Jeff,
The result is an output of another code and it will be too long or
unnecessary to show all I'm I did to arrive at the given data frame.
Since my single line code works for Jeff, I had to take a second look
and try to get it working for me. I then read the data frame using
d<-re
Works for me. Apparently you are not showing us everything you are doing. As
Bert recommended, you need to use the dput function rather than dumping numbers
into the email if we are to know how your data are stored in memory which will
affect what results you get. I highly recommend using the re

Thank you for looking at this.

Hello,
I'm glad it helped.
One more thing. I forgot to set the column names, if you want to get
them from the data, try something like this:
nms <- lapply(s, function(.s) .s[grepl("[[:alpha:]]+", .s)])
nms <- sapply(nms, paste, collapse = ".")
names(daT3) <- nms
daT3
Hope this helps,

You can use the vector of integer cluster numbers with silhouette()
from the cluster package.
https://www.rdocumentation.org/packages/cluster/versions/2.1.0/topics/silhouette
But note that silhouette as an assessment metric makes roughly the
same assumptions that k-means does about the data stru

I would guess that you first need to convert your textual dates to a
date-time object via as.date, but as you failed to provide a reproducible
example (e.g. via dput) I may be wrong. Maybe others may have greater
insight.

A new package "sclr" for fitting the "scaled logit" model from Dunning
(2006) is available.
CRAN: https://cran.r-project.org/package=sclr
Github: https://github.com/khvorov45/sclr
I appreciate any feedback.

There are two character classes that you can try, [:blank:] and
