get the first row ?
Hi Ragia, This is a bit cryptic. "ISINFCluster" looks like a 50 element logical vector with two TRUE values. "all" looks like a 50 element numeric vector of counts for each value. "firstclass" contains the 20th and 27th elements of "all", selected with "ISINFCluster". As "firstclass" is a two element named vector, there is only one "row" and that includes the entire object.

Dear group
kindly
I have a logical data type
ISINFCluster:
1 2 3 4 5 6 7 8 9 10 11 12 13 14
FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE
15 16 17 18 19 20 21 22 23 24 25 26 27 28
FALSE FALSE FALSE FALSE FALSE TRUE FALSE FALSE FALSE FALSE FALSE FALSE TRUE FALSE
29 30 31 32 33 34 35 36 37 38 39 40 41 42
FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE
43 44 45 46 47 48 49 50
FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE
and I want to get just number of records from those that has the value true, thus
firstclass<- all[ISINCluster]
where all is numeric object
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29
1 1 2 1 3 1 1 2 5 4 1 6 8 1 2 1 3 3 2 13 1 4 2 4 7 1 14 1 1
30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50
1 1 2 2 1 1 2 2 2 9 3 1 1 3 6 1 4 1 3 9 2
the firstclass containes the following
firstclass
20 27
13 14
And I could not get the first row..
head(firstclass)
20 27
13 14
