I have a question in R.

In directory H:/Delta_angle
I have 19 files like this:

ALA.delta
ASN.delta
ASP.delta
CYS.delta
GLN.delta
GLU.delta
HIS.delta
ILE.delta
LEU.delta
LYS.delta
MET.delta
PHE.delta
PRO.delta
SER.delta
THR.delta
TRP.delta
TYR.delta
VAL.delta

I want to read these files to 19 data sets in R. All these data sets have "P","AA",index","delta" columns I want to do histogram for variable "delta" in each data set, and label the histogram by mean, standard deviation and number of observation for
"delta" column.
Do you know how to do these in R?

thanks

Aimin Yan
