A few questions:
1. How do I read in a file that is located on my desktop? I accidentally cleared the $Path as well...oops.
2.I have a data file w/ thousands of points:
The first seven columns are acceleration data time-stepped at .005 seconds. They run 1-7 (row 1), 8-14 (row 2) etc.Code:0.0237 0.0237 0.0237 0.0237 0.0238 0.0238 0.0237 1 0.0234 0.0229 0.0234 0.0240 0.0257 0.0288 0.0264 2 0.0243 0.0263 0.0307 0.0270 0.0232 0.0199 0.0158 3 0.0203 0.0235 0.0241 0.0247 0.0242 0.0233 0.0265 4 0.0322 0.0272 0.0224 0.0180 0.0124 0.0215 0.0278 5 0.0322 0.0380 0.0352 0.0310 0.0271 0.0212 0.0262 6 0.0302 0.0289 0.0245 0.0275 0.0362 0.0879 0.1695 7
I would like to see a plot of acceleration versus time w/ this but the 8th column is just row numbers so I dont want that?
Thanks
Set the path to the file, read the data, select all the data that's not integers using a pure function construct, form the list of points {data,i*0.005}, plot the points.Code:$Path = Append[$Path, "c:\Math Help Forum"]; data = ReadList["data1.txt", Number]; newdata = Select[data, Not[Element[#, Integers]] &] points = Table[{newdata[[i]], 0.005 i}, {i, 1, Length[newdata]}] ListPlot[points, Joined -> True]
