Hello
Consider following dataframe named df
var1 var2 var3
3771 354 565
654654 963 6677
775 147 657754
df <- read.table('clipboard', header = TRUE)
df
#find indexes with '77' in var 1
myIndexes <- grep( glob2rx("*77*"), df$var1)
myIndexes
#find actual values of seach above
myValu <- grep( glob2rx("*77*"), df$var1, value=TRUE)
myValu
#find all '77' in entire dataframe
all77 <- lapply(df, function(x)grep( glob2rx("*77*"), x, value=TRUE))
all77
#OR indexes
all77ind <-lapply(df, function(x)grep( glob2rx("*77*"), x))
all77ind
Hope that helps
With best regards
Denis
