similar to: Dont show zero values in line graph

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

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

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

Hello all, Frustrated and i know you can help I need to drop the last numeral of each of my values in my data set. So for the following i have tried the ?substring but since i have to specify the length, but because my data are of varying lengths it doenst work so well Data<-c("1131", "1132", "1731" ,"1732" ,"1821" ,"1822",

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, Please consider the following: TotEmp<-c(19,6,1,1,8,44,2,33,48,1) ClusterType<-c("AGF","CNS","OSV","RTL","RTL","TRN","REL","ACC_CLUST","RTL","WHL") Taz<-c(0,0,0,100,100,100,101,101,102,103)

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 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

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.

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

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:",

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.

Hi guys, I have a crap load of data to parse and have enjoyed creating a script that takes this data and creates a number of useful graphics for our area. I am unable to figure out one summary though and its all cause I dont fully understand the apply family of functions. Consider the following: #Create data

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,

Hello all, I am trying to use the tapply function to sum some values and change the column names of the resulting vector.

Well im thoroughly frustrated after 25 minutes of checking and rechecking my path. What do i not know about loading a mdb that is keeping me from loading my data. i have loaded the Hmisc library and pointed it too my data using mdb.get and continue to get the following error. Error in system(paste("mdb-tables -1", file), intern = TRUE) : 'mdb-tables' not found Which i

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 '

Hi everyone, I have been using R too long to have to ask this but here i am. How do i create a separate bin for the 0 value? So for: #Create data frame DF<-data.frame(A=0:20) #Create label vector labs<-1:6 #Create buckets and label DF$Cut<-cut(DF$A,c(0,4,8,12,14,16,20),labels=labs,include.lowest=TRUE) I want the 0(zero) value to be in a separate bin. Sorry for the lame post...
