Dear group, Here is my df :
df3 <- structure(list(DESCRIPTION = c("COPPER May/10", "COTTON NO.2 Jul/10", "CRUDE OIL miNY May/10", "GOLD Jun/10", "ROBUSTA COFFEE (10) Jul/10", "SOYBEANS Jul/10", "SUGAR NO.11 Jul/10", "SUGAR NO.11 May/10", "WHEAT Jul/10", "SPCL HIGH GRADE ZINC USD", "STANDARD LEAD USD", "CORN May/10", "SILVER May/10", "WHEAT May/10", "COFFEE C Jul/10", "CORN Jul/10", "HENRY HUB NATURAL GAS May/10"), POSITION = c(0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0), prix = c(-14, 3.74999999999997, 5.22500000000005, 21.6999999999998, 68, -8.5, 2.72999999999999, -0.900000000000002, -64.25, -41, -118, 7.75, 45.300, 0, 4.75000000000003, -1.5, -0.0490000000000013)), .Names = c("DESCRIPTION", "POSITION", "prix"), row.names = c(NA, -17L), class = "data.frame") I want to remove all the dates in $DESCRIPTION. I was thinking using something like this: >df3$DESCRIPTION<- gsub("here is a regex expression","",df3$DESCRIPTION). Can't write the pattern argument in regex. Any help would be appreciated.
