Merging columns with a key that tells which column should be prioritized based on suffix R
I have the following dataframe:
set.seed(123) df <- data.frame(col.dfA=rnorm(8,40,2), col.dfB=rnorm(8,20,2), colt=rnorm(8,100,20), pr.dfA=rnorm(8,20,2), pr.dfB=rnorm(8,30,2), priority=c("dfA","dfB","dfA","dfA","dfB","dfA","dfB","dfB"))
Now I would like to merge
col.dfA
&col.dfB
andpr.dfA
&pr.dfB
intodf$col
anddf$pr
respectively. Thedf$priority
column gives indication which column values should be used in each row. Ie. in the 1st, 3rd, 4th and 6th rows, columns with suffixdfA
should be prioritised. In remaining rows columns with suffixdfB
should be prioritised. The solution needs to be applicable for larger scenarios with dozens of columns and hundreds of rows.Initial dataframe:
col.dfA col.dfB colt pr.dfA pr.dfB priority 1 38.87905 18.62629 109.95701 18.74992 31.79025 dfA 2 39.53965 19.10868 60.66766 16.62661 31.75627 dfB 3 43.11742 22.44816 114.02712 21.67557 31.64316 dfA 4 40.14102 20.71963 90.54417 20.30675 31.37728 dfA 5 40.25858 20.80154 78.64353 17.72373 31.10784 dfB 6 43.43013 20.22137 95.64050 22.50763 29.87618 dfA 7 40.92183 18.88832 79.47991 20.85293 29.38807 dfB 8 37.46988 23.57383 85.42218 19.40986 29.23906 dfB
Expected result:
col colt pr priority 1 38.87905 109.95701 18.74992 dfA 2 19.10868 60.66766 31.75627 dfB 3 43.11742 114.02712 21.67557 dfA 4 40.14102 90.54417 20.30675 dfA 5 20.80154 78.64353 31.10784 dfB 6 43.43013 95.64050 22.50763 dfA 7 18.88832 79.47991 29.38807 dfB 8 23.57383 85.42218 29.23906 dfB

Copy Multiple DBF files content to other DBF files
I have 200 DBF files (related to Windows program) that I need to transfer their content to different DBF files that have the same names.. , i.e. file1.dbf content should be transferred to file1.dbf content from different folder, I need to do that for all 200 files. I can only find manual solution but its slow , I need to do it for all at once. The reason I need to do that is because the files have some protection or I don't get it, if I simply replace them the program will give error realated to db, other easier solution is welcome.
What really happened - The files are used in accounting software. I have created the backup with backup function from the software, it was done daily automatically. Restore function is protected for free version. I can only manually restore the files, but the backup files work only on the exact software version as protection. The thing is that the software is 100% free as long as you don't update it, I didn't knew that until I selected the update menu option. Now the software is updated but it asks me for license key which is very expensive. I have the backup files, but as the restore function is blocked I can't restore it with the program. I can only replace the files myself from the backup , its a directory that is backed up. The problem is that it has some protection on files itself , they are not recognized but only if I manually edit the files with DBF Manager software, if I open a default software file and paste the content from backup file it works, but I have many files.Now I'm stuck with company documents locked not been able to access it
Thank you

Read the last element of an array in a file
This code reads and writes the first element of an array.
print "Gimme a path to a file : " filename = gets.chomp ipf = File.open(filename, "r") ipd = File.open("ps.txt", "w") t = [] while(line = ipf.gets) if line.strip.length == 0 ipd.puts "#{t[0]}" t = [] else t << line.strip end end ipd.puts "#{t[0]}" ipd.close
How do I repair this code so that it will read and write the first element of the last array regardless of whether the array has an empty space after or not?
