1 2@b@cAbout 3 4 5@bDescription 6 7Displays a window with useful information about xldlas, including copying 8policy, warranty (nada), ftp site locations, source code data, compilation 9date, and so on. 10 11 12@bNotes 13 14The author's e-mail address should be used primarily to find out where to 15send donations :) 16 17@bSee Also 18 19Help --> See License 20 21 22 23@b@cLoad 24 25 26@bDescription 27 28Used to load in a file previously saved in xldlas's .lda format. If you 29don't have reams of data lying around in this format then you'll have to 30import ASCII data (see below) or input data by hand. The Load command erases 31the dataset in memory, and so can cannot be used if there is unsaved (or 32undropped) data. 33 34 35@bNotes 36 37If you have data that you want to get into xldlas, use the Import command. 38It works, and it's safer than trying to hand build (or awk) .lda files. 39 40@bSee Also 41 42File --> Save, File --> Import, Data --> Input 43 44 45 46@b@cSave 47 48 49@bDescription 50 51The save command will store all of the current variables, variable names, 52variable descriptions, the dataset label, and the current value for a 53missing observation in an xldlas's .lda format file. This file can later be 54fed back into xldlas using the Load command. 55 56 57@bNotes 58 59The file format is very specific, so don't edit .lda files manually unless 60you know what you are doing. 61 62 63@bSee Also 64 65File --> Load 66 67 68 69@b@cAppend 70 71 72@bDescription 73 74Append will load a new .lda file into xldlas without first erasing the data 75in memory. This can be very useful for building large datasets out of 76smaller ones. If a variable name in the dataset being appended exactly 77matches the name of a variable already in memory, then that data will be 78appended onto the end of the existing variable. If there is no name match, a 79new variable is created with name taken from the file being appended. 80 81 82@bNotes 83 84None 85 86@bSee Also 87 88File --> Load 89 90 91 92@b@cImport 93 94 95@bDescription 96 97Import can read in space delimited ASCII data. The incoming file should 98consists of nothing but float values seperated by whitespace and newline 99characters. If you choose the columns option, then xldlas will create a 100variable for each column present in the file and read subsequent data into 101those variables. The row option will create a new variable for each line in 102the file. 103 104In both cases, any line which begins with a non numeric character 105(0-9, +, -) will be ignored. The routine uses ASCII codes to check 106the first non-whitepsace character on each line, so if you're using 107some operating system that does non-standard stuff vis-a-vis cahracter 108codes you may have problems. If you do, please contact the author and 109he'll try and figure out a solution. 110 111 112@bNotes 113 114As of v0.70, the import routines have been vastly improved. They are 115virtually guaranteed not to fail (the author has succesfully imported 116a Linux kernel image: meaningless data, but it didn't freeze xldlas). 117 118 119@bSee Also 120 121File --> Load 122 123 124 125@b@cQuit 126 127 128@bDescription 129 130This will exit xldlas. It can only be selected if there is no unsaved data 131in memory. If you don't want to save the data, then drop it (see Data --> 132Drop) 133 134 135@bNotes 136 137Unlike pushing the close window button, this menu option does not ask you if 138you are sure you want to quit. 139 140@bSee Also 141 142File --> Save, Data --> Drop 143
