Re: [R] Reg: To change the x axis label in ts.plot function
Hi Upananda,
First, the date sequence you are using doesn't match the dates you
specify in your post. The code below may give you what you want:
# make up some prices
price<-c(seq(60,25,length.out=25),seq(25,70,length.out=54))+rnorm(79)
pricet <- ts(price, start = as.Date("2020-01-27"),end=as.Date("2021-07-26"),
frequency=1/7)
plot(pricet,xaxt="n")
axis_dates<-as.Date(c("2020-06-30","2021-01-01","2021-06-30"))
axis(1,at=axis_dates,labels=format(axis_dates,"%d/%m/%Y"))

https://stackoverflow.com/questions/49679699/time-series-plot-change-x-axis-format-in-r Is as good a solution as possible using ts I think.

[R] Reg: To change the x axis label in ts.plot function
Dear All, I have the data set with daily dates (5-days trading in a week) and price data. I want to change the x axis labels to the plot. I am using ts.plot function to plot my data. My data spans from 2020-01-27 to 2021-07-30. I want to change it to D-M-Y first. Then I want to show all the dates with a one week gap in my x-axis label. The following code I am using: pricet <- ts(price, start = c(2020, 27), frequency = 260) plot.ts(pricet) Please advise me how to achieve the desired result. I have attached my data and the plot which I am currently getting with ts.plot.

Post-mortem debugging for non-interactive R scripts can be enabled by
setting options(error = quote(dump.frames("A_SUITABLE_FILE_NAME",
to.file = TRUE))) in your script. See ?dump.frames for more information.
When you're running command-line R interactively, the main tools at
your disposal are traceback() and browser() (see their respective help
pages). There are two main ways to use the browser: (1) by setting the
debugging flag on a function via debug(function) or debugonce(function)
-- you will land in the browser when the function is called -- and (2)
by setting options(error = recover), which will launch the browser at
the time of the crash, letting you walk the stack and inspect the
values of various variables.
For more information on pure-R debugging, see The R Inferno book:

Re: [R] difference between script and a function....
dear Ivan, Thanks for the reply. One last question: 1. How do you debug if there is an error, particularly if I run the script from the BASH prompt? The closest I have come to debugging a script is when I source the script in Rstudio. There everything is intiutive...but from the Linux prompt?

Using its cache() function, you can save intermediate objects into *.rds files in a relatively transparent manner. By default, they are stored in a subdirectory of the working directory. A downside is that I haven't come up with a useful cache expiration strategy yet. A more involved approach that will also let you access your intermediates is provided by the "targets" package, not only on CRAN but also peer-reviewed by rOpenSci. -- Best regards, Ivan [[alternative HTML version deleted]] __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.

Re: [R] difference between script and a function....
Dear Simmons, Thanks a lot. One more question: 1. If there is some error in the script, the error will be output to the stdout? Or to the file that it creates for saving the output of the script?

The execution environment for a script is the global environment. Each R script run from a shell will be given its own global environment. Each R session has exactly one global environment, but you can have several active R sessions. 2. Using return in a script instead of a function will throw an error Error: no function to return from, jumping to top level 3. You can use print(), cat(), and writeLines() to write to the output. It does not save your R objects before it exits the script. You could use save() or save.image() to save your objects, or possibly saveRDS() if you are only looking to save one object.

[R] difference between script and a function....
Dear members, I will be running scripts automatically in RHEL with crontab. I want to know the differences between running a script and a function. in particular: 1. An execution environment will be created for the function. what about a script? Is the execution environment the global environment? 2. What happens if I use return() at the end of a script? 3. I came to know that when you use R CMD BATCH, a file will be created and the output will be saved to the file. How do I output what I want to output in a script? Should I use return()? Will ALL the intermediate objects be stored ? 4. When I run a script, it will have access to the objects in the global environment right? i.e I can use all the functions in the global environment, right? 5. Any links to resources for further information? How do i access the relevant documentation? ANy help will be greatly appreciated... thanking you, yours sincerely, AKSHAY M KULKARNI [[alternative HTML version deleted]] __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
