I have an image stored on my hard drive and I want to import it into an R-Markdown document I have.
I have 2 copies in both PNG and JPEG format, but for the life of me I cannot figure out how the read functions work in the "png" and "jpg" packages.
Can someone please help?
The easiest way is to use the
format, here name does not matter, is just a name that you want to give to a figure, as an example you can use an internet image such as:
that will translate in your knitted documento to
for an image in the same folder as your working directory you can just put the name of the image:
if not you have to add the path to the folder that depends on your OS on how to specify it, I recommend you to just put your image in the folder of your working directory. And just one last thing, I usually have less problems with PNG files than JPG for some reason
If you need more help with that just let me know

Can anybody help me how to resolve this error?
Error in setwd("C:\Users\user\Downloads\Vendor_Data") :
cannot change working directory
data <- read.csv("Vendor_Data")
It may be that you are trying to change the working directory to a file, not a directory. Try instead:
setwd("C:\Users\user\Downloads")
and then explicitly mention the file extension:
data <- read.csv("Vendor_Data.csv")

So when I run R and try to read a file, it gives me an error like this
Error message
But I definitely have my file in my directory. As I can tell below photo.
working directory
How can I solve this problem??
You definitely don't have that file in your directory as I can tell from your photo.
However it seems you don't understand what you're looking at. It seems you want to use the rubber.df dataset from the R330 package which you can load using data(rubber.df) and then use by calling rubber.df

Can anyone help me to changing order for pages under unit of each course,please your help will be really appreciate.I tried a lot but fail to get the meta value for each pages.
If I understand your problem well, this plugin may be a solution: https://wordpress.org/plugins/simple-page-ordering/
If you are still having this problem, you are one of many.
The only solution I have found so far is this work-around plugin, I believe it is called "Emanaku's Reordering of Pages in CoursePress Pro 2.0". Here's a link to the WPMUDev topic: https://premium.wpmudev.org/forums/topic/coursepress-plugin-for-reordering-pages
Read the description carefully, you need at least CoursePress version 2. Note - this plugin is probably going to stop working in the future, as it depends on the current structure of CoursePress which is likely to change dramatically.

I've searched the forum but can't find anything on this. I have the following line in a file by itself:
FormState = new ReactiveState();
Other files in the package can't reference FormState. How do I make it package-scoped instead of file-scoped?
Make sure the files referencing your global variable are added after the file with the declaration. For example:
api.addFiles('file-with-global-var.js');
api.addFiles('file-using-global-var.js');
If these were reversed, you'd probably see an error. Also make sure to check they are both accessible from the same environment. For example:
api.addFiles('file-with-global-var.js', 'client');
api.addFiles('file-using-global-var.js', 'server');
would obviously be a problem, as the server code couldn't read a variable declared only on the client.

I am using Crystal Report that comes with VS 2005. I need to Export the Crystal Report To Text File. What's the way to do it.
Looks like they've taken away that enumeration for some reason. I suppose you could loop through the underlying recordset, and dump the contents into a text file yourself. What a PITA though...
I think the closest you will get to a text file is to export as csv.
ExportFormatType.CharacterSeparatedValues
Now, the thing that sucks about this is if the report is designed to look good (with page footers, headers, etc) the csv file will contain all that. So you would need to make a minimal report to get a good csv export. Which really almost makes it seem more logical to dump to text file yourself.
