kandi X-RAY | readxl Summary

readxl is a C++ library typically used in Analytics, Data Visualization applications. readxl has no bugs, it has no vulnerabilities and it has low support. However readxl has a Non-SPDX License. You can download it from GitHub.

The readxl package makes it easy to get data out of Excel and into R. Compared to many of the existing packages (e.g. gdata, xlsx, xlsReadWrite) readxl has no external dependencies, so it’s easy to install and use on all operating systems. It is designed to work with tabular data. readxl supports both the legacy .xls format and the modern xml-based .xlsx format. The libxls C library is used to support .xls, which abstracts away many of the complexities of the underlying binary format. To parse .xlsx, we use the RapidXML C++ library.

This is what I think you're looking for. First, it isn't built into that plotting function to do this, but you can create these labels dynamically.

It ended up being a bit easier if I changed the name of stratum to Quartile. If that's what you're labeling it, this shouldn't be too big of an issue.

R mutate won't add columns

Asked 2022-Mar-16 at 20:02

I am trying to use the mutate function to form three new columns to my data. I have tried defining some of the data and it has not changed it. I have looked at previous examples but all seem to use a group function before using mutate. I think I do not need to create a group before using mutate as it would not fit with my data.

Here is the R code I am using:

So this turned out to be a little more complicated than I first thought, in part because of t(), which is really designed to work with matrices. Fortunately, I was able to find some guidance elsewhere on SO, where I found transpose_df(). Though this works, I imagine this could be cleaned up a bit.

How to build a Shiny app that opens excel and worksheet?

Asked 2022-Mar-10 at 23:32

I am trying to build an app that lets the user to upload an excel file, choose a worksheet and some data (i.e column) and make graphs.

I have prepared a dummy app to show my probelms. I have two of them...

The update of the input for the worksheet name is not working. Althogh the input field is updated by updateSelectInput it always rewrite to the default value (I think there is a nesting issues but I try to solve it for more then two days, without any luck...)
I don't know how to set the input of the worksheet to be able to receive any name later, now it always jumps back to the first WS (If I set choices = c('') or choices = 1 it gives an error that there is no such WS)

Answered 2022-Mar-10 at 23:32

I added more than you asked for to try and solve this, so I hope the extra steps are helpful or insightful. I also don't have xlsx since I don't have java, so I used openxlsx instead.

I can spot a few issues with your current code. For example, your reactive has an observeEvent in it, which observes the ws_var input, and is meant to update the worksheet names based on when a worksheet is selected. It might work better if you observed the xls_input instead.

What I provided may be a bit more robust. I added show/hide features using shinyjs, seeing as each step is dependent on the previous step. Meaning the following step will only show when the previous is selected. Additionally, not all columns in the tables are numeric. For output$calc, it will try and sum those characters which for me causes a problem. So I added an if statement which will look to see if the column is numeric or not (which uses dplyr)

The following script creates two shiny apps: The child_app is running in a seperate background R process (depending on how you deploy your app this might not be needed), which can be controlled (filtered) via query strings.

The parent_app displays the child_app in an iframe and changes the query string (iframe's src) depending on the user accessing the app (permission level):

How to read and merge only the second sheet from a number of excel files (xlsm) in R?

Asked 2022-Feb-08 at 18:57

I have a working directory with a large number of xlsm files (600ish). I need to merge all of these files into one dataframe, but ONLY the second sheet of the excel file. Since there are a lot of files, ideally I would use a loop, but I'm struggling with how to do this. Right now I have this code, which is obviously not working. Any thoughts on how to best do this would be greatly appreciated.

You were close. You just need to slightly alter your lapply statement, so that the function and parameter are separated by a column.

Install readxl

The easiest way to install the latest released version from CRAN is to install the whole tidyverse. NOTE: you will still need to load readxl explicitly, because it is not a core tidyverse package loaded via library(tidyverse).
