Hi, Imagine a vector x with elements (1,2,1,1,3,5,3,3,1) and a vector y with elements (2,3). I need to find out what elements of x match any of the elements of y. Is there a simple command that will return a vector with elements (F,T,F,F,T,F,T,T,F). Ideally, I would like a solution that works with dataframe colums as well. I have tried x==y and it doesn't work. x==any(y) doesn't work

Hi, I am writing a for loop that creates one object, say 'outn' on every round of the loop. I would like the name of each object to include the index of the loop as in, for example: out1, out2, out3, ... And I would like the naming of the object to take place automatically as the loop moves through? Similarly, I would like to be able to call different objects (in1, in2, in3,

Dear R-ers! I have a badly organized data base in Excel. Once I read it into R it looks like this (all variables become factors because of many spaces and other characters in Excel):

Dear list, I have the following text to parse (originating from readLines as some lines have unequal size), st = c("START text1 1 text2 2.3", "whatever intermediate text", "START text1 23.4 text2 3.1415") from which I'd like to extract the lines starting with "START", and group the subsequent fields in a data.frame in this format: text1 text2

I have a an STI table which acts_as_tree, that has a large number of classes/types. My common fields are: id parent_id name description with 4 more text fields, I could cover most of my classes if I could redefine the name of the field like this. text1 AS address1 text2 AS address2 text3 AS zipcode For one class and text 1 AS model_number text2 AS vendor Is there a construct that will allow

I am very sorry for such a simple question, but I am struggling with "split". I have the following data frame: x<-data.frame(A=c(NA,NA,NA,NA,"split",NA,NA,NA,NA,"split",NA,NA,NA,NA,"split",NA,NA,NA,NA),

Hi all, I have a large number of text strings to search for enumerated items. However, I am receiving this error message even though I thought that I properly escaped the special character closed parenthesis: > Count<-str_count(text3,keywords) Error in stri_count_regex(string, pattern, opts_regex = opts(pattern)) : Syntax error in regexp pattern. (U_REGEX_RULE_SYNTAX) === Here is

Hi, I have: a <- matrix(c(0,1,0,1),nrow=2) b <- matrix(c(1,1,1,0,0,0),nrow=3) c <- 1 d <- c(1,0,1) And I would like to join them in an object 'thing' so that I can access a, b, c, or d through an index in a for loop. For example: thing[4] would return [1] 1 0 1 Note however, that I have many of these 'thing' components. So many that a command like thing

Hi, If I have a vector: junk <- c(2,0,0,3,0) and want to access, say, all the elements that are greater than zero. I just do: junk[which(junk>0)] Now, If I have a list: jlist <- list(NULL,c(1,0),NULL,c(1,2,3), NULL) and want to access all the elements that have length greater than zero, I know how to find the elements with: which(sapply(jlist,length)>0) But how do I get a

Hi, If I have a data frame A with the following format: Day1 Day2 Day3 Day4 1 1979-11-02 1979-11-03 1979-11-04 <NA> 2 1979-12-06 <NA> <NA> <NA> 3 1979-12-13 1979-12-14 1979-12-15 1979-12-16 4 1979-12-20 <NA> <NA> <NA> And a date "1979-12-14", for

Hi, Anyone knows what would be a short way of extracting a month from a date in numeric or integer format? months("1979-12-20") returns "December" in character format. How could I get 12 in numeric or integer format? Thanks! G. [[alternative HTML version deleted]]

Hi, I have a vector 'data' of 58 probability values (bounded between 0 and 1) and want to draw a probability density function of these values. For this, I used the commands: data <- runif(58) a <- density(data, from=0, to=1) plot(a, type="l",lwd=3) But then, when I try to approximate the area under the plotted curve with the command: area <- sum(a$y)*(a$x[1]-a$y[2])

Hi, I have a matrix BEE and want to find the row and column numbers of the minimum value in that matrix. The command which(BEE==min(BEE)) returns only one value which, I take, is the position of the minimum in a vector with as many elements as the matrix. Is there a quick and simple way of getting row and column numbers? Thanks, Gonçalo [[alternative HTML version deleted]]

Sorry for the off topic, but don't a better resource. I'm not great at scripting, but need a quick script to modify a file. I have a long file that has lines like this: some text some text2 CN=DATA.OU=XYZ.O=CO some text3 some text4 And this repeats, but XYZ changes. "DATA" is always called data. (it's being renamed basically) I need to change the middle line but leave

Hi, I have a vector of strings (class character) with 6 elements (length 6). I call it 'names'. "Graham Chapman" "John Cleese" "Terry Gilliam" "Eric Idle" "Terry Jones" "Michael Palin" And I want to turn it into another vector of strings called 'shortnames' with the same length. The new vector should look like:

I have 2 vectors, x and y and have done an xy plot. I want to plot the label (name?) of the vector on the plot rather than the value. text(x,y, labels = x) gives me the value of x. text(x,y, labels = labels(x)) gives me something like c("text1","text2"..) plotted for each point text(x,y, labels = names(x)) gives nothing print(x) gives me [,1] text1

Colleages I am running R 2.1.0 on a Mac (same problem occurs in Linux). In some situations, I have mixed text/numeric data that is stored as characters in a matrix. If I convert this matrix to a dataframe, the numeric data becomes factors, not what I intend. TEXT <- paste("Text", 1:4, sep="") NUMBERS <- 10 + 4:1 MATRIX <- cbind(TEXT,

Hi, 'true_name' is a list of numerical, matrix, and text items I do pass_name <- "true_name" and pass the name of the list to a function so that the character class variable 'passed_name' contains the name of the list called 'true_name' Inside the function, how can I get a specified element from the list? For example, if I want to get

I have the following javascript being called on my site and I am getting a Javascript error - "Object doesn''t support this property or method".
