QUESTION
I know that C:\Windows\System32\WDI
exists and has contents. We need to copy these contents from hundreds of machines for security analysis. We tried:
ANSWER
Answered 2022-Mar-23 at 18:06The likeliest explanation is that the inability to find the directory is due to running in 32-bit PowerShell sessions on 64-bit systems: the System32
directory that 32-bit processes see doesn't have a WDI
subdirectory.
You have two options:
Make sure that you use 64-bit PowerShell sessions everywhere.
Construct the directory path conditionally, so that in 32-bit sessions it accesses the directory via the
SysNative
folder, which refers to the true, (paradoxically named) 64-bitSystem32
folder; usingGet-ChildItem
as an example:
QUESTION
I am using a data frame from WDI and am attempting to clean a merged dataset.
One of the two merged datasets only has values at 2000,2005,2010, and so I would like to have a subsetted data frame that only includes those years (for each country etc).
My code is as follows:
WB_Merge1 = subset(WB_Merge, select = c(year==2000 | year==2005 | year==2010))
However, when I run it in R it creates a data frame that now has all 5502 observations but no variables?
Could anyone help? Many thanks.

I want to print code without \n
on the result.
This is my code
ANSWER
Answered 2021-Aug-27 at 13:21I had this same problem and I got an answer here.
It's is because the line you read is always followed by a \n character. You need to remove it. Hence, just replace that last part of your code with this. .strip() will do for you. str(current_location).strip("\n")
Whenever you read a line from a text file, it adds a \n character to tell that new line started from there. You need to remove that while printing or it will mess up with your current statement

I am using WDI library to run commands regression analysis for 5 countries.
I try to create dummy variables with the help of command named as "dummy_cols".

QUESTION
I am learning R and ggplot2 but one thing that really confuses me is the parameters available to the aes function.
I am proficient in programming languages such as Python and Java. In such programming languages you define a function, and its parameters are also pre-defined and you expect so many parameters that a function can take.
But the use of the aes function seems to be very different here, except its 'x' and 'y' parameters. For example:

QUESTION
I'm trying to find the mean of a column called GDP within a dataset called WDI. I've tried using mean(WDI$GDP)
but I think it's not working because some of the values are "..". I'm not able to change these values in the dataset; is there any way to get the mean while excluding the ".." values?
ANSWER
Answered 2021-Jul-27 at 21:01The ..
means it is a character
vector. One option is to wrap with as.numeric
so that all the character elements are converted to NA
, and then use na.rm = TRUE
in mean

QUESTION
I am new in r and this may sound like a silly question but I was trying to join two tables by country
but got nan
in some as their names do not match. (data from covid19.analytics & world bank data - WDI)
Now I have created a mapping table for country names that didn't match with country names from both table.
How can I join them to replace nan for the mis-matched country name rows ?

Answered 2021-Apr-05 at 17:31We could do a join on the 'mapping_tbl' first, coalesce
the 'Country.Region' and the 'tbl_ts_all_long', then use the OP's code
