plot more plots from one matrix
Hi r-help-bounces at r-project.org napsal dne 03.12.2010 16:56:37:
I solved the 1? problem with this command:
matrix2plot2[,"sensor_data"]<-as.numeric(as.character((matrix2plot2[,"sensor_data"])))
In fact before the previous command I if write: str(matrix2plot2[,"sensor_data"]) I get: Factor w/ 10 levels "131.22","148.532",..: 4 6 4 6 9 8 9 8 3 1 ... And after the command
matrix2plot2[,"sensor_data"]<-as.numeric(as.character((matrix2plot2[,"sensor_data"])))
if I write: str(matrix2plot2[,"sensor_data"]) I get: num [1:16] 30.4 31.2 30.4 31.2 50.1 ... ----------------------------------------- but I can't solve the 2? problem....
What is 2o problem? Regards Petr
