[R] Finding and removing non-printable ascii characters in a file
Hi! I'm completely confusing myself attempting to solve this one. Is there a simple way of removing particular ASCII characters from a CSV file using R. Hopefully something simpler and faster than cycling through each individual character and comparing them to a list of characters to remove then deleting as necessary. As always, any help would be appreciated. Thanks!

[R] RODBC - XLSX files - dropping/clearing sheets
Hi! I'm manipulating XLSX data using RODBC, however a limitation which appears to be driver based is that you can't clear or drop sheets from the XLSX files, as per the following example: library(RODBC) xlsx-odbcDriverConnect(DRIVER=Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb);DBQ=c:\\documents and settings\\desktop\\testxlsx.xlsx; ReadOnly=False) sqlClear(xlsx,newsheet2,errors=TRUE) [1] [RODBC] ERROR: Could not SQLExecDirect [2] HY000?Þêÿÿ\003 -5410 [Microsoft][ODBC Excel Driver] Deleting data in a linked table is not supported by this ISAM. sqlClear(xlsx,newsheet2,errors=TRUE) [1] [RODBC] ERROR: Could not SQLExecDirect [2] HY000?Þêÿÿ\003 -5410 [Microsoft][ODBC Excel Driver] Deleting data in a linked table is not supported by this ISAM. I'm wondering if anyone has or knows of a work around for this beyond converting the sheets to CSV files. For context, I'm trying to update data on about 20 spreadsheets as a daily event, pulling data from MySql, formatting it, then overwriting the existing data on the spreadsheets. This is the last piece of the puzzle. Until the next puzzle. Thanks!

[R] joining multiple lists
Hi! I'm reading and cleaning data from multiple excel spreadsheets. All the data has the same column names and the natural next step is to join the lists of data together to make one list for reporting purposes. I had thought that c(file1data, file2data) would do the trick but that seems to append the new columns to the list so I end up with duplicate column names col1 col2 col3 col1 col2 col3 rather than consolidated column data. It's obviously a straight forward operation, but damned if I can find a straight forward explanation on the web. Any assistance would be most appreciated! Thanks!

[R] Finding and moving files
Hi! I'm at the very beggining of my R experience and I'm hoping someone can point me in the right direction. I want to create a script that locates all files within a directory tree that have certain keywords in their file names, checks these against files in another location, then copies files that don't already exist in that other location. I'm currently tralling through the help reference but I've yet to find anything that might do the trick. Any ideas? Thanks!
