Hello I need to make my R file into a CSV file. I have searched stackoverflow for different methods to accomplish this, but nothing is working. Each time, it says:
Error in is.data.frame(x) : object 'refine_clean' not found
My file is definitely named refine_clean.R. I have linked a screenshot here:
R Studio CSV Error Message
Your file is named refine_clean but you have no data.frame or object named refine_clean, which is what write_table and write.csv are looking for.
based on the screen shot, it is not clear what you want to produce. If it is the last object you created (d5), you may want something like this
write.csv(d5, "refine_clean.csv")
you cant convert all your file as an csv, you need to select the object, like d5
write.csv(d5,file = "name_of_the_file")

I'm trying to get R to read data from a txt file, but the file is not properly made, so it's giving me lots of errors.
Ideally, I'd like to be able to extract a dataframe to be able to work with from this, but I trully don't know how to.
The files are all in this link.
An example with any of them would work.
Thanks a lot!
I do not have any expertise on R and I have to convert RData files to CSV to analyze the data. I followed the following links to do this: Converting Rdata files to CSV and "filename.rdata" file Exploring and Converting to CSV. The second option seemed to be a simpler as I failed to understand the first one. This is what I have tried till now and the results along with it:
>ddata <- load("input_data.RData")
>print(ddata)
[1] "input_data"
> print(ddata[[1]])
[1] "input_data"
> write.csv(ddata,"test.csv")
From the first link I learnt that we can see the RData type and when I did str(ddata) I found out that it is a List of size 1. Hence, I checked to see if print(ddata[[1]]) would print anything apart from just "input_data". With the write.csv I was able to write it to a csv without any errors but it has just the following 2 lines inside the CSV file:
"","x"
"1","input_data"
Can you please help me understand what am I doing wrong and show a way to get all the details in a csv?
The object ddata contains the name of the object(s) that load() created. Try typing the command ls(). That should give you the names of the objects in your environment. One of them should be input_data. That is the object. If it is a data frame (str(input_data)), you can create the csv file with
write.csv(input_data, "test.csv")
I'm trying to load an Excel workbook with a large number of tabs into R, do some analysis, and then export the results back into Excel. I'm using the openxlsx package because of some of the features of that package that are not easily accessible using other packages (such as the ability to create "comments" in the output file, color code the tabs, and work with 64-bit R).
When I try to read in the workbooks, I sometimes get the following error message (or something similar):
Error in unzip(xlsxFile, exdir = xmlDir) :
cannot open file 'C:/Users/MENDEL~1/AppData/Local/Temp/RtmpIb3WOf/_excelXMLRead/xl/worksheets/sheet5.xml': Permission denied
This error message doesn't always show up - but sometimes it will appear and the program crashes.
Does anyone have any ideas how to fix this problem? I don't know why the program sometimes thinks it doesn't have permission to access the sheets.
Thank you in advance!
I can think of two possible scenarios for this error:
Scenario 1:
C:/Users/MENDEL~1/AppData/Local/ (This looks like you are trying to read a temporary file)
Solution:
If that is the case try moving the file to a different location like desktop and make sure that you update your working directory accordingly.
Scenario 2
C:/Users/MENDEL~1/AppData/Local/Temp/RtmpIb3WOf/_excelXMLRead/xl/worksheets/sheet5.xml' (Looks like there is some issue with Sheet5 which is of type .xml and the openxlsx does not allow you to read .xml)
Solution:
Check if there is some issue with the format or contents of sheet5 in the file that you are trying to read.

I am using R to read in a file, therefore I use read.csv. The files come from a dataset and are all tagged by a date. However, some dates are missing. For date X, I want to read in a file "X". Because some files are missing, R gives me "Error in a file(file, "rt") : cannot open the connection". Instead, I want R to automatically read in file "X-1" if "X" is nonexistent (or "X-2" if "X-1" is also nonexistent etcetera). Thus, I am looking for some kind of "IFERROR" statement to get around this. I could not find this kind of statement, does anyone know how to detect a "rt" and act on it? Regards, Margot
I got a question about reading a file into data frame using R.
I don't understand "getwd" and "setwd", do we must do these before reading the files?
and also i need to print some of the columns in the data frame, and only need to print 1 to 30,how to do this?
Kinds regards
getwd tells you what your current working directory is. setwd is used to change your working directory to a specified path. See the relevant documentation here or by typing ? getwd or ? setwd in your R console.
Using these allows you to shorten what you type into, e.g., read.csv by just specifying a filename without specifying its full path, like:
setwd('C:/Users/Me/Documents')
read.csv('myfile.csv')
instead of:
read.csv('C:/Users/Me/Documents/myfile.csv')
