similar to: format numbers into percentages

Hi, I need to convert general numbers to percentages in R to create a boxplot for purposes of comparison. Can you please tell me how I can do that? My data is attached as a csv file. Thanks. Daniel

Hi, Does anyone know how one could format numbers using 1000 separator in R? For example, format 1000 as 1,000 and 100000 as 100,000, etc. Thanks, -- Tom [[alternative HTML version deleted]]

Dear friends, I have a table like this, I have A B C D ... levels, the first column you see is just the index, and there are different numbers in the table. A B C D ... 1 0 2 1 0 2 1 0 2 1 3 2 3 0 0 4 0 0 1 0 5 0 2 3 1 ... I want to calculate the frequencies or the percentages of the numbers in every column. How do I get a table like this,

Hi, I am constructing a contingency table using xtabs. The function works great: mo yr Sep Oct Nov Dec 1950 -7.164486e-02 3.152674e-02 -1.283389e-02 1.570382e-01 1951 3.054293e-02 4.665234e-02 -2.445499e-04 8.720204e-02 1952 3.937034e-02 -4.790636e-02 5.022616e-02 1.180279e-01 but I wonder if there is an argument I can pass to xtabs

Hi, I am looking for an elegant way to transform a vector into percentages of values that meet certain criteria. store<-c(1,1.4,3,1.1,0.3,0.6,4,5) # now I want to get the precentages of values # that fall into the categories <=M , >M & <=N , >N # let M <-.8 N <- 1.2 # In my real example I have many more of these cutoff-points # What I did is: out <- matrix(NA,1,3)

Hello everyone, I have two questions: 1.) I would like to generate random percentages that add up to 100. For example, if I need 5 percentages, I would obtain something like: 20, 30, 40, 5, 5. Is there some way to do this in R? 2.) I would like to insert vectors of specified length into a larger vector of specified length randomly, and fill the gaps with zeroes. For example, if I have 3 vectors

Hello I've got some data and I want to fit a binomial glm. The problem is that I don't have the number of successes or failures, I have only the percentages. If I want to make all these numbers integers, I have to multiply them for 1000, because there are some low percentages (0.05%). Besides, I don't know if this is correct. Any help? Thanks in advance, and sorry for my english

Dear R-users, Though it's a silly thing to ask, but I'm not getting a way out. I wish to find the percentage distribution for a data vector 'stop'. The coomand below is giving the frequency distribution. May I know the option to see the percentages instead of frequencies. Similarly, what option I should put in a histogram plot to see the percentages instead of frequencies?

I an stumbling on something that is probably very simple, but I cannot see the solution. I have an object generated by the table () function and want to recompute this table so each cell represents the percentage of the corresponding row sum. Of course a dedicated function can be written (which I have done), containing the necessary loops etc., but there should be a simpler way. I'd

Hi all, though i know this is a simple question, i really hope someone could. I am just trying to compare percents respectively the difference in percents by a simple test. t.test usually compares means and is working like it is supposed to be. Now i wonder how i can use a test in R to test for significant difference between two percentages.

I have a vector V. sum(V) = 100, i.e. it's percentages. length(V) is large. I wish to generate samples (with replacement is fine), integers, in the range 1:length(V) who's distribution is driven by the distribution implied by the percentages in V. V is unsorted, but that could change. I'd rather not be too specific about the distribution of V. I can certainly solve the

Hi All, I am in the annoying position of having to present some data to someone who seems to be somewhat less than numerate. I need to label the y-axes of a multhist with the y-axis labeled not as counts but as percentage of a population. Plotting the standard histogram is in a way fine, all I need is to: -- have a left-handside y-axis labels for pop 1 and a right-handside y-axis labels for pop2

Hello! I promise I looked into help files before asking. Still cannot figure it out. I think it's because I am totally confused what packages use lettice, which use trellis, etc. Sections 1 and 2 below produce the data and the data to plot. My question is about barplot in Section 3. I am trying to: 1. add only horizontal gridlines and manipulate the type and color of that line. tck = 1 is not

Hi, I am trying to get percentages in a more elegant way. I have a data.frame with locations and values (counts) of species at that location. Each location is repeated for each species i have values for and i would like to get percentages of each species at that location. I am not sure if i am clear in my explanations so i will paste my code below: ##################### > x locat val 1

Dear R-users, I'd like to create filenames in a mask "file000.dat" numbered from 1 to e.g. 123. The last problem I'm dealing with is creating the sequence of numbers with equal length, i.e. 001, 002,.... 023, 024,.... 122, 123. The closest I got is by a repetition: Sequence <- c(1:123) for(i in c(1:length(Sequence))) { print( paste(rep("0",

I can think of several ways to blunt force hard code what I want but I imagine there is a command or two that can be easily combined to do this: I have a data frame with about 23000 observations. There first variable is the group to which the observation belongs (about 500 different groups). The second variable is a response for each observation that is a 1,2,3,4 or 5. I want to be able to

Hi, Suppose I already have two plots on the same screen, and I want to draw lines in each of them. Is that possible in R? It seems that once you have two plots on the screen, you can only draw lines in the the last plot, never the 1st. Here is what I mean: #some data y1=rnorm(1:3) y2=rnorm(1:3) #draw two plots on the same screen par(mfrow=c(2,1),oma = c(6, 0, 5, 0)) par(mar=c(0, 5.1, 0, 5.1))

I hesitate to post this question in the light of recent threads, indeed I have hesitated for several weeks, however I have come to a full stop and really need some help if I am going to progress. I am a new user of R for medical statistics. I have attempted to read all the relevant documents, but would welcome any suggestions as to what I have missed. I am trying to contruct "table 1"

I am wondering if there is any procedure to write a particular value in Percentage format, still maintaining it's numeric character. for example I want to write '.33' as '33%' regards, thanks in advance --------------------------------- [[alternative HTML version deleted]]

Hello! I have a question about my lattice barchart that I am trying to build in Section 3 below. I can't figure out a couple of things: 1. When I look at the dataframe "test" that I am trying to plot, it looks right to me (the group "Total" is always the first out of 5). However, in the chart it is the last. Why? 2. How can I make sure the value labels (on y) are not
