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
how can I got it?
thanks in advance

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 I have this numeric object allrecords 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 how can I extract only records between 9 and 5 values only and put the record number n a vector it should be vector thanks in advance Ragia [[alternative HTML version deleted]]
It looks to me like you need to understand subscripting in R. One place (among many) to learn subscripting is: http://www.burns-stat.com/documents/tutorials/impatient-r/ Pat On 10/05/2015 10:26, Ragia Ibrahim wrote:> 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 > > > how can I got it? > thanks in advance > Ragia > > > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >
Hello, You should learn about indexing in R. Read the pdf R-intro.pdf that comes with your installation of R. allrecords[5 <= allrecords & allrecords <= 9] should do it. Hope this helps, Rui Barradas Em 10-05-2015 11:00, Ragia Ibrahim escreveu:> Dear group > I have this numeric object > allrecords > 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 > > > how can I extract only records between 9 and 5 values only and put the record number n a vector > > it should be vector > thanks in advance > Ragia > > > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list -- To UNSUBSCRIBE and more, see > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >
