            'what' must be a function or character string in R error message
            Asked 2022-Apr-08 at 14:36

            I am plotting different umaps. I have a part of the code that worked yesterday, however today I get the error message: Error in, lapply(2:ncol(nn_idx), function(i) as.vector(rbind(nn_idx[, : 'what' must be a function or character string"

            My code is the following:

            Maybe you have overwritten the primitive function c ? R lets you do that, I was able to replicate your error bellow, and to fix it you can just remove c and it will revert back to the primitive function, so you can try that, please let me know if it fixes your problem.



            Merging cells, in the same column, in the same df- Python
            Asked 2022-Jan-26 at 15:29

            I am attempting to merge two cells together. The reason for this is due to the fact that every unit under 'Chassis' should be an alphanumeric (ABCD123456) however the PO provided occasionally shifts the last number to the next row (no other data on said row) making the data look like this Example I initially tried to create a statement that looked at the cell, confirmed it was less one number, then would look at the next cell, and merge the two. Never got that to even come close to manifesting any results. I then decided to replicate the data frame, shift the second data frame(so the missing number is on the same row), and merge them together. This is where I am now. Error Msg This is my first real bit of code in Python so I am fairly certain I am doing inefficient things so by all means let me know where I can improve.

            Currently I have this...

            Col1 Chassis Other Columns... Other Columns 2... Nan ABCD12345 ABC 123 Nan 6 Nan Nan Nan WXYZ987654 GHI 456 Nan QRSTU654987 Nan 789 Nan MNOP999999 XYZ Nan

            End Goal is this...

            Column Lost when Concatenating Dataframes with Pandas?
            Asked 2022-Jan-01 at 21:52

            I'm writing a program to scrape through a folder of PDFs, extracting a table from each that contains the same data fields. Sample screenshot of the table in one of the PDFs:

            The goal of the program is to produce a spreadsheet with all of the data from each PDF in a single row with the date of the PDF, and the common fields as the column headers. The date in the first column should be the date in the PDF filename. It should look like this:

            When I extract out the data into a dataframe and add column headers for "Field" and the date of the report, it looks like this:

            It is hard to say exactly since your examples are hard to reproduce, but it seems that instead of adding a field you are changing the column names. try switching these rows in your function:



            python tabula error encoding for pdf read
            Asked 2021-Dec-30 at 16:51

            I would like to export tables from a PDF in a dataframe or take a csv file. But I cannot read a PDF file with Python. What do I need to do? I tried reading the PDF with Python tabula:



            Answered 2021-Dec-30 at 16:51

            In comments I suggested the contents of the PDF were at fault since the Greek words had not been encoded correctly,

            looks like a poor quality PDF from that many warnings Thus I first suggest before investing any more time in tuning for a suspect source you 1st verify that cut and paste that table may in fact result in something worth capturing. My initial assessment is you might get just the second column with numbers and there is some hidden Greek words that are not showing but the rest is garbage, thus the only valid extraction could be by using an OCR method.

            Thus the best approach to correct that PDF first would be to use OCR, however many attempts at OCR are also mislead by the existing contents of the PDF.

            So in that case, the best working solution is to OCR afresh from images. As an example I printed the first page badly, however, it was for proof of concept that an image route may get you closer to your goal.

            I only have currently a means to export as monochrome tiff via 200dpi fax, you would get much better results using grey-scale as .png .pbm or .tif[f] (NOT jpg)

            Once converted to plain text docx or xlsx etc. it should produce something like this, ignore the poor headings in this sample, that was a byproduct of using such a crude attempt in monochrome with a dotty background.

            Clearly the result needs some clean-up to match the input such as spell checking, but should then be good enough for textual processing by any further means. A better choice of image resolution and a target output such as csv might have got a better usable result, thus closer answer to your question.

            Answered 2021-Dec-29 at 07:34

            As per documentation of Tabula-py, I guess you need Java 8+. And java version "1.7.0_80" is Java 7 I guess.

            Kindly try to update Java version to 8+ and try again.



            How to split a Pandas DataFrame column into multiple columns if the column is a string of varying length?
            Asked 2021-Dec-03 at 03:21

            I have a Pandas DataFrame that was created by reading a table from a PDF with tabula. The PDF isn't parsed perfectly, so I end up with a few table columns smushed into one column in the resulting DataFrame. The issue is that one of the table columns in the PDF is text, so there are sometimes one word and sometimes two words that compose the column. Example:



            Answered 2021-Dec-03 at 03:21

            You can try using str.rsplit:

            Splits string around given separator/delimiter, starting from the right.

            If you have only one dataframe with Section ID name (or are interested only in the first dataframe with this column) you can iterate over the list returned by read_pdf, check for the column presence with in df.columns and break when a match is found.



            Matching characters from two 1D arrays into a 2D array
            Asked 2021-Nov-25 at 07:05

            Essentially, I've created a vigenere cipher. Vigenere Cipher matrix

            It's a method used for coding messages. I've created the 2D array for the Vigenere cipher array. I receive a message in a form of a .txt file to be encoded. I then convert this into a regular '1D character array'. Essentially reading the text and putting every single character into a new array.

            I then also get input from the user for the key, this key is then taken and repeated to match the length of the character array. So now I have a 'key array'.

            How a Vingere Cipher works is that the key's first letter and the texts first letter is matched. So on the X-Axis is the 'message' and on the Y-Axis is the 'key'.

            For example, if I do key: road

            and message: cars

            the encrypted message would be: torv,

            I would get T, because I started with R on the Y-Axis and matched it to C on the X-axis.

            This is how I setup my Vigenere Cipher. where 'alphabet' is this. I'm just having trouble 'matching' the characters of the two arrays (encryption key) and (message) to my Vigenere Cipher, then saving that input as an array inside a method to be used later on. Currently, I'm not too worried about capital letters and so on.

            Vigenere cipher code:
