hi everybody,

i try to extract a part of name to a date :

like : "VGT1_VGT2_CONTR_B020030401.H0V0.MIR" to "20030401"

but the beginning of the files changes

i have a list of files:

 [,1]                                

[1,] "VGT1_CONTR_B020020301.H0V0.MIR"
[2,] "VGT1_VGT2_CONTR_B020020611.H0V0.MIR"
[3,] "VGT1_VGT2_CONTR_B020030401.H0V0.MIR"
[4,] "VGT1_VGT2_CONTR_B020030711.H0V0.MIR"
[5,] "VGT1_VGT2_CONTR_B020031211.H0V0.MIR"
i try the function "get()" and "assign()" but without succeed

i know it's easy in C but in R i don't know the way

if you have an idee

thanks ,

Jonathan Charrier
