x |
an object of type |
logX |
should the horizontal axis be on log scale? |
add.legend |
set to TRUE if legend should be printed in top right hand corner. Legend will contain names of variables in data.frame, if specified, otherwise will be numbered from 1 to p in order encountered in original input matrix x |
add.labels |
set to TRUE if labels are to be added to curves at leftmost side. If variable names are available, these are plotted, otherwise, curves are numbered from 1 to p in order encountered in original input matrix x |
lty |
usual 'lty' plotting parameter. |
col |
usual 'col' plotting parameter. |
