R help - Jun 2010 - selecting and excluding files through a pattern

I have the following files list:
> list.files()
 [1] "Prostate-Cancer_cvs_Dir"                            
 [2] "Prostate_Cancer-miRNAs&Genes.Pathway.xml"           
 [3] "Prostate_Cancer_Pathways-miRNAs-GeneTargets-Dir"    
 [4] "Prostate_Cancer_Pathways-miRNAs-GeneTargets-Dir.zip"
 [5] "Prostate-miRNAs.OrganTargets.txt"                   
 [6] "Prostate_Organ-miRNAs-GenesTargets-Dir"             
 [7] "Prostate_Organ-miRNAs-GenesTargets-Dir.zip"         
 [8] "Prostate_Organ-miRNAs-Targets.xml"                  
 [9] "Prostatic_Neoplasm-miRNAs.DiseaseTargets.csv-KO"    
[10] "Prostatic_Neoplasm-miRNAs.DiseaseTargets.txt"       
[11] "Prostatic_Neoplasms-miRNAs-GeneTargets-Dir"         
[12] "Prostatic_Neoplasms-miRNAs-GeneTargets-Dir.zip"     
[13] "Prostatic_Neoplasms-miRNAs.xml"                     

I'd like to find the pattern expression which selects only the directories
excluding the one whose
pathname contains "csv".
I tried:
> list.files(pattern="Prostate*Dir")
But I do not know how to exclude the names containing the string "csv"
at the same time.

Thank you for any help,
Maura

Hi Maura,

Try  list.files(pattern = 'csv')
