kandi X-RAY | beepr Summary
beepr is an R package that contains one main function, beep(), with one purpose: To make it easy to play notification sounds on whatever platform you are on. It is intended to be useful, for example, if you are running a long analysis in the background and want to know when it is ready. A derivative function, beep_on_error(), wraps an expression and will only beep if an error occurs when that expression is evaluated. This package was previously called pingr and included a ping() function. It has been renamed in order to not be confused with the Unix tool [ping] For the rationale behind beepr see the original announcement:

QUESTION
Description
This issue appears to apply to vectorised and loop approaches to renaming several files. Vectorised approach used in reprex below. The bug only seems to present when filenames do not contain meaningful or alphanumeric strings.
Summary
Existing files prior to file.rename:
"1.R" "2.R" "3.R" "4.R" "5.R".
Existing files following file.rename:
"6.R".
Expected output:
"2.R" "3.R" "4.R" "5.R" "6.R"
Reprex
...ANSWER
Answered 2021-Mar-20 at 09:03Is 6.R actually the content of 1.R?
I think you are seeing 1.R renamed to 2.R and over-writing 2.R in the process. The new 2.R to 3.R etc.

QUESTION
Similar issues have been discussed on this forum (e.g. here and here), but I have not found the one that solves my problem, so I apologize for a seemingly similar question.
I have a set of .txt files with UTF-8 encoding (see the screenshot). I am trying to run a topic model in R using tm package. However, despite using encoding = "UTF-8" when creating the corpus, I get obvious problems with encoding. For instance, I get < U+FB01 >scal instead of fiscal, in< U+FB02>uenc instead of influence, not all punctuation is removed and some letters are unrecognizable (e.g. quotations marks are still there in some cases like view” or plan’ or ændring or orphaned quotations marks like “ and ” or zit or years—thus with a dash which should have been removed). These terms also show up in topic distribution over terms. I had some problems with encoding before, but using "encoding = "UTF-8" to create the corpus used to solve the problem. It seem like it does not help this time.
I am on Windows 10 x64, R version 3.6.0 (2019-04-26) , 0.7-7 version of tm package (all up to date). I would greatly appreciate any advice on how to address the problem.
...ANSWER
Answered 2020-May-02 at 10:20I found a workaround that seems to work correctly on the 2 example files that you supplied. What you need to do first is NFKD (Compatibility Decomposition). This splits the "fi" orthographic ligature into f and i. Luckily the stringi package can handle this. So before doing all the special text cleaning, you need to apply the function stringi::stri_trans_nfkd. You can do this in the preprocessing step just after (or before) the tolower step.
Do read the documentation for this function and the references.
QUESTION
tidyr::fill() isn't filling values in my tibble. Here is a reprex:
ANSWER
Answered 2020-May-01 at 23:08We can change the .direction to downup or updown as the output shows the NA are at the beginning and if we use "down" as option, it will fill the NA values with the preceding non-NA so the ones at the top remains as such because there are no preceding non-NA. With 'downup', it will first do the fill in the downward direction that is filling NA with non-NA preceding, then does the reverse in upward i.e. filling NA with non-NA succeeding. Also, with using 'Date' as one of the grouping columns, there are some groups with only NA and that would make the fill to return NA. In this case, perhaps, we can group by only 'State'

I am trying to download the text of newspaper articles for textual analysis using R. I have a large list of urls to individual articles and want to use Rvest to extract each of these articles' text and title and convert it into a data frame.
As an example, I have a subset of my dataset with articles from The Guardian:

I added Sys.sleep(2) to the parse_texts function and was able to go through my list of URLs.

ANSWER
Answered 2018-Sep-26 at 14:10LinearLayout does not allow children views to be overlapped.
You should use RelativeLayout (or FrameLayout, etc) instead of LinearLayout as the parent if you want to display FABs above (overlapping) other views.
In your case, set the root layout to RelativeLayout. You may need to make other adjustments though.
QUESTION
I am trying to use beepr in my Rscripts to tell me when they are done.
But the beep never comes.
here is an example script saved as test.R:
...ANSWER
Answered 2018-Apr-29 at 07:53The reason for this behaviour is because the sound played by beep() does not block the session, but is played by the session, and as soon as the session is over the sound stops. If you run this in an R session then the session continues, and so the sound is played, but if you run this with Rscript the session exits thus immediately cutting the sound short.
A workaround is to delay the closing of the session allowing the sound to finish playing:
QUESTION
I have time series data in a fixed-width-file where observation rows (n varies depending on the sample size) occur under a "header" row which contains the important meta data (ie. sample number, date, etc.). Both types of rows contain alphanumeric characters. It looks something like this (strings shortened for ease of reading:
...ANSWER
Answered 2017-Sep-14 at 13:42Here is a solution using tidyverse.
It makes a new column with just the header rows, and then fills the rows without a header with the header from above. At the end you can paste the columns together if you want.
