Re: [R] [Rd] Problem with accessibility in R 4.2.0 and 4.2.1.

Note that the issues with the Rscript editor have been fixed in 
R-patched and R-devel.

Thanks everyone for all the suggestions. Of course, the optimal solution 
would be to figure out what is going on in Rgui, but, as is always the 
case, the blind user use case is a fairly niche one. I appreciate all 
the suggestions for finding an immediate solution to my problem.
I don't use any kind of IDE for working with R since I simply haven't 
found one that is accessible or that i understand how to use. There is a 
plug-in for the Eclipse IDE I installed a few years ago, but I didn't 
understand the first thing about how it was to be used. So I've just 
always worked with an editor open in one Window and R in another,
working interactively in R or bouncing over to the editor for more 
complex things and sourcing code into R as necessary. However, I only 
use the R console in Rgui. I went and had a look at Rterm, which I have 
never used on Windows; I've only ever used it when ssh-ing into Linux 
systems to use R. However, I've just found out that Rterm does a number 
of fairly important things that probably mean I can just use it instead 
of Rgui:

1. You can paste from the clipboard into the Rterm prompt;
2. It has a command history;
3. If you plot something, it opens a Window to draw the plot (I never 
realised it could do this and had always assumed Rgui was needed for 
this); and
4. It opens the HTML help if you ask for help on windows. I only ever 
saw it display text help on Linux, but I was logged in remotely. 
Text-based help is fine when ssh-ing into a machine, but HTML help is 
much nicer to read and navigate.


I think I'll just switch over to Rterm for a while, but I can also check 
out ess, which I wasn't aware of.


Thanks a lot,
Andrew.

Re: [R] Need help plotting

[Jim Lemon]

Hi David,
No, read.table converts a text representation of data into a data frame object.

Re: [R] How to set default encoding for sourced files

[Andrew Hart via R-help]

Thanks. The --encoding option indeed makes it all work. Rscript --help 
does not show the --encoding option in the list of options.


And yes, you are right. I was using R 4.1.2 when I first wrote to the 
list. I was experiencing a technical  issue with R 4.2.1 which was 
preventing me from switching over to it but I have a satisfactory 
solution to the problem now and have just moved to R 4.2.1. It seems 
that, on Windows at least, R 4.2.1 does indeed use utf-8 as its native 
encoding. I didn't realise this. At any rate, it looks like merely 
upgrading solves my encoding concerns without the need to set options or 
specify the encoding with Rscript. Very nice and kudos to the R 
developers for taking the leap!


Thanks everyone for your help.

Cheers,
Andrew.

If you're using R for Windows, I'm surprised this issue would come up 
since R 4.2.0 added support for UTF-8. At least on my own Windows 
machine, I can run exactly what you wrote and not have any issues. Are 
you using an older version of R?

Thanks everyone. Setting encoding in options in Rprofile.site has taken
care of it.

Curiously, it doesn't seem to solve the whole problem for Rscript
though. I checked that Rscript is indeed picking up the default
encoding
from options, but it's complaining about seeing an unexpected input in
dat$línea <- 
immediately following the l when I run
Rscript myfile.R.
So, it would appear that Rscript is not using source to read in the R
script. Mind you, if I do
Rscript -e source('myfile.R')
it works properly just like in Rgui.

Once again, Thanks heaps.

Cheers,
Andrew.

Re: [R] Need help plotting

[DFP]

Do I need that read.table if the tst dataframe already exists in my 
system?  If so, why?

--

Hello,

You have to load the packages involved:


library(dplyr)
library(tidyr)
library(ggplot2)


then run the full sequence. Though this is not important, if you are
pivotting columnns named y1 and y2, why not name the result just y?


pivot_longer(-time, names_to = "y")


And here is complete code, runs in a fresh R session.


tst  <- read.table(text = "
time y1 y2
1  18:55 30 19
2  18:56 30 19
3  18:57 29 19
4  18:58 31 19
5  18:59 28 19
6  19:00 28 19
7  19:01 28 19
8  19:02 28 19
9  19:03 28 19
10 19:04 28 19
11 19:05 29 19
", header = TRUE)

library(dplyr)
library(tidyr)
library(ggplot2)

tst %>%
    mutate(time = paste(Sys.Date(), time),
   time = as.POSIXct(time)) %>%
    select(time, y1, y2) %>%
    # reshape to long format
    pivot_longer(-time, names_to = "y") %>%
    # now plot
    ggplot(aes(time, value, color = y)) +
    geom_line() +
    geom_point() +
    scale_color_manual(values = c("orange", "skyblue")) +
    # make datetime labels
    scale_x_datetime(date_breaks = "1 mins", date_labels = "%H:%M") +
    theme_bw()


Hope this helps,

Rui Barradas

Espero sea de utilidad.
