[R] How to parse a really silly date with lubridate
Hi,
I have data file which generated by an otherwise very nice (diabetes
log) app, but exports dates really silly.
After reading the enclosed mwe.csv into R like so
MWE <- read_delim('mwe.csv', delim = ';') %>%
select(Date) %>%
print()
this comes out as:
# A tibble: 2 × 1
Date
1 9. Jul 2022 at 11:39
2 10. Jul 2022 at 01:58
No matter what I try I am not able to parse this inside R to get at
proper dates (I have loaded tidyverse and lubridate).
I can easily do somethig
csvq -d ';' -t '%e. %b %Y at %H:%i' \
'SELECT Date as oridate,
DATETIME_FORMAT(Date, "%Y-%m-%d %H:%m") AS date
FROM mwe'
+---+--+
|oridate| date |
+---+--+
| 9. Jul 2022 at 11:39 | 2022-07-09 11:07 |
| 10. Jul 2022 at 01:58 | 2022-07-10 01:07 |
+---+--+
and hence could easily do something like
csvq -d ';' -t '%e. %b %Y at %H:%i' \
'ALTER mwe
SET Date = DATETIME_FORMAT(Date, "%Y-%m-%d %H:%m")'
but would rather like to be able to do it inside R and would therefor
appreciate any advice in this regard.

In my opinion, creating variables in the global environment

collision. How about the following:
1. Put the countries in a vector: c('Namibia', 'Germany', ...)
2. Use lapply() to get a list of objects returned from your PICTURE

3. To save the pictures into individual files, loop over the list. You
can use setNames on the step 1 or 2 to make it a named list and keep
the country names together with their pictures:
for (n in names(pictures)) {
dev.new()
print(pictures[[n]])
ggsave(paste0(n, '.png'), ...)
dev.off()
}
(You can also use the png() device and plot straight to the file,
avoiding the need to draw the plot in the window for a fraction of a
second and for ggsave().)
4. Use the grobs= argument of grid.arrange() to pass the list of

Re: [R] Best cross-platform OSS GUI CSV management application?

Re: [R] seeking latex peace
It's not a TeX issue veven, it's a Fedore issue :-)-O pdflatex is standard in all (most) TeX distributions. TeXLive is probably the standard TeX distribution for Linux, it has a Windoze version and a MacTeX version (or rather two, a complete and a basic). I have used both on Linux and the Mac respectively for many years. It is upgraded every year completely and in the interval you can use the TeX Live Manager to update packages and to install missing ones. It is currently frozen and the new version is supposed to come out on 2014-07-01. That said, while some Linux package managers for some Linux distributions are very up-to-date, most are not. el On 2014-05-25, 11:17 , Jim Lemon wrote: Hi all, I realize that this is not an R question, but in attempting to build a new version of a package, I have encountered the error: Error in texi2dvi(file = file, pdf = TRUE, clean = clean, quiet = quiet, : pdflatex is not available As I could not find any way to install pdflatex (it didn't appear on a yum search), I tried a method that claimed to install pdflatex via a package named texlive.

Re: [R] SQL vs R
So, some feedback. Have installed MariaDB 10.0.10 on the Linux box. That speeded things up. Changed from InnoDB/XtraDb to Aria. That speeded loading of the data up. Have installed MariaDB on the iMac. That speeded things up more. Tried to tune MariadDB's config. Didn't speed things up much, but for the query buffer. Figured out Replication (from the linux box to the iMac). This slowed loading down somewhat. Played with the SQL. Speeded things up significantly. Played with the inxdexes. Did not speed things up much. Found what I could do in data.table that was faster than SQL and did that. Obvious increase in speed. My R processing time came down from 35 to 6 1/2 minutes. Removed all large tables before saving (and once the raw data was no longer required). That reduced RData from 150MB to 7KB. Pushed the table and image generation into a second R file. This takes 4 seconds. The corresponding LyX/LaTeX/Beamer/KnitR runs in 12 seconds. Installed RStudio. Nice. Adding new SQL queries adds between 30 and 90 seconds in the input R file, next to nothing to the presentation generation. I could not care lass how long the input takes, even hours, as long as I can save the analysis results and not the data into the RData. el PS: Ordered a MacPro :-)-O.

From experience, it is not unlikely to find bottlenecks in generic algorithms that can be made 10-100 times faster. Here is *one* example illustrating that even when you think the code is fully optimized you can still squeeze out more: http://wiki.r-project.org/rwiki/doku.php?id=tips:programming:code_optim2 So, start profiling your code to narrow down the parts that takes most of the CPU time. help(Rprof) is a start. There is also a Section 'Profiling R code for speed' in 'Writing R Extensions'. Good old verbose print out of system.time() also helps. My $.02 ...or 2000-3000USD if it was bounty?! ;) /Henrik Thanx for any tip [[alternative HTML version deleted]] __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. -- Dr. Eberhard W.

Re: [R] How to preserve date format while aggregating
Erich,
how does the data look, when it comes from SQL?
And why not extract the data with SQL directly, so you don't
have this issue in the first place?

Thanks, I've already tried that. The problem is, that the original date is
not restored when I change the numeric back to date. I get a totally
different date.
Maybe it has something to do with the original date format. My data are
directly imported from a SQL-database. The date column to which I want to
apply the aggregate function has the two classes POSIXt and POSIXct.
Changing the column to class Date before applying the aggregate function
did not help. I still get a different date, when I transform it back to
class Date.
I would be glad, if someone knew a more elegant way to extract the rows with
minimum/earliest date per subject.

Try changing the 'class' of the numeric result back to Date:
x - as.Date('2008-09-08')
x
[1] 2008-09-08
y - as.numeric(x)
y
[1] 14130
str(y)
num 14130
class(y) - Date
y
[1] 2008-09-08
str(y)
Class 'Date' num 14130

Hi
I have a dataframe in which some subjects appear in more than one row. I
want to extract the subject-rows which have the minimum date per subject.
I
tried the following aggregate function.
attach(dataframe.xy)
aggregate(Date,list(SubjectID),min)
Unfortunately, the format of the Date-column changes to numeric, when I'm
applying this function. How can I preserve the date format?
Thanks
Erich
