Hello all, I have what i feel is a unique situation which may not be resolved with this inquiry. I have constructed the below data set so that i may give an example of what im doing. The example works perfectly and i have no issues with it. My problem arises with my actual data, which includes another 11 columns of data (used in later analysis) and a total of about 7000 cases(rows). i

Hello All, I would like to select records with identical IDs then sum an attribute then and return them to the data frame as a single record. Please consider Acres<-c(100,101,100,130,156,.5,293,300,.09) Bldgid<-c(1,2,3,4,5,5,6,7,7) DF=cbind(Acres,Bldgid) DF<-as.data.frame(DF) So that: Acres Bldgid 1 100.00 1 2 101.00 2 3 100.00 3 4 130.00 4 5 156.00 5

Hi guys, Cant seem to find a solution for this. I am looking for a substitute for cut that can transform character vectors. So as cut would be used below to transform YearCat-> YearCat2 base on Year and vector Ag<-c("00-'70","'71-'75","'76-'85","'86-'09") using 'cut '

Hello all! I have a problem to group my data (years) in 10 years classes. For example for year year decade 1598 1590-1600 1599 1590-1600 1600 1590-1600 1601 1600-1610 --- my is like this> [1] 1598 1599 1600 1601 1602 1603 1604 1605 1606 1607 1608 1609 1610 1611 1612 [16] 1613 1614 1615 1616 1617 1618 1619 1620 1621 1622 1623 1624 1625 1626 1627 [31] 1628 1629 1630 1631 1632 1633

Hi all For the data below, I would like to return a logical value indicating differences in the data. #Create data Data..<-data.frame(a=rep(1,10),b=c(rep(1,9),2),c=c(rep(1,8),2,2)) a b c 1 1 1 1 2 1 1 1 3 1 1 1 4 1 1 1 5 1 1 1 6 1 1 1 7 1 1 1 8 1 1 1 9 1 1 2 10 1 2 2 So what I want is to return logical value telling me if all the values are the same. So the result would be a b

Hi everyone, I am posting this because i know its easy and i cant for the life of me figure out how to do it though i have tried and through a ridiculously complex loop made it happen. I need to convert some list elements of NULL value to 0s so they mesh with my data frame properly. So for A<-list(1,NULL) returns [[1]] [1] 1 [[2]] NULL Would instead return [[1]] [1] 1 [[2]] [1] 0

Hello all! I have a problem to extract values greater that for example 1820. I try this code: x[x[,1]>1820,]->x1 Please help me! Thank you! The data structure is: structure(c(2.576, 1.728, 3.434, 2.187, 1.928, 1.886, 1.2425, 1.23, 1.075, 1.1785, 1.186, 1.165, 1.732, 1.517, 1.4095, 1.074, 1.618, 1.677, 1.845, 1.594, 1.6655, 1.1605, 1.425, 1.099, 1.007, 1.1795, 1.3855, 1.4065, 1.138, 1.514,

Hi , SO i have been on a role of asking simple questions lately. So much for feeling like im getting this R business. I wrote a script 2 weeks ago that utilized "proportion" to turn values in a table (from "table") into proportions to then graph. I now get an error that proportion is not a function so im confused. I ran the script a few times and im thinking maybe i had

Hey R'rs, So im sick of dealing with ESRI products and am looking to stream line a process i now use GIS to do using R. I have made a lot of maps using R but have not yet seen a map that puts pie charts within the map to help represent data like the attachment. http://r.789695.n4.nabble.com/file/n2318816/template1.bmp I found Tanimura et al. work "Proportional Symbol Mapping in

Okay everyone heres a likely softball for someone. Consider the following data frame: #Create data x<-rep(c(1,15),10) y<-rnorm(20) z<-c(rep("auto",10),rep("bus",10)) a<-rep(c(1,1,2,2,3,3,4,4,5,5),2) #Create Data frame Df<-data.frame(Source=x,Rate=y,Bin=a,Type=z) I want to create a new column the equals the sum of the Rates for each type (1,15) by Bin. A

Hello all, I cannot seem to figure out this seemingly simple procedure. I want to sort a data frame by a specified character vector. So for : df.. <- data.frame(Season=rep(c("Summer","Fall","Winter","Spring"),4),Obs= runif(length(rep(c("Summer","Fall","Winter","Spring"),4)))) I want to sort the data frame

Hi everyone, I looked around the list for a while but couldn't find a solution to my problem. I am storing some results to a simulation in a list and for each element i have two separate vectors(is that what they are called, correct my vocab if necessary). See below Version1_<-list() for(i in 1:5){ Version1_[[i]]<-list(First=rnorm(1),Second=rnorm(1)) } What I want is to put all

Hi all, I have toyed with this for too long today and in the past i used multiple lines of code to get at what i want. Consider the following: All i need to do is subset Pc to the values that do not equal Pc.X. The first attempt doesnt work because i have unequal lengths. The second attempt doesnt give me an the right answer.

Basic question, looked through the forum and documentation but didnt see a solution. So consider O<-c(1:20) D<-c("1:","2:","3:","4:","5:","6:","7:","8:","9:","10:","11:","12:","13:","14:","15:","16:",

Hey everyone, Im getting better at plotting my data but cant for the life of me figure out how to show a line graph with missing data that doesnt continue the line down to zero then back up to the remaining values. Consider the following x<-c(1:5,0,0,8:10) y<-1:10 plot(0,0,xlim=c(0,10), ylim=c(0,10),type="n",main="Dont show the bloody 0 values!!") lines(x~y,

Hi everyone I have some records that include a date attribute for the date and time but i need to separate the data and analyze it separately in GIS by Month and Year, so i need to pull these attributes out and create their own attribute field. So the input: RawData2.. returns ID period_end_date 1 22 9/10/2007 0:00:00 2 44 2/2/2006 0:00:00 and i need to get ID period_end_date

So after about 4 hours struggling with Try and TryCatch I am throwing in the towel. I have a more complicated function that used logspline through iterative distributions and at some point the logspline doesnt function correctly for some subsets but is fine with others so I need to be able to identify when the error occurs and stop curtailing the distribution and I think this Try or TryCatch

Hello all , This is a pretty simple question I think but cannot find an answer on the list or in my brain. I would like to iterate through a loop and use a vector of strings to name a number of list elements. For instance #Create vector of strings Et<- c("ACC","RTL","WHL") MeanValues_ <- list("ACC" = 1000, "RTL" = 2000,
