count data with a specific range
I would like to prepare the data for barplot. But I only have the data frame now. x1=rnorm(10,mean=2) x2=rnorm(20,mean=-1) x3=rnorm(15,mean=3) data=data.frame(x1,x2,x3) If there a way to put data within a specific range? The expected result is as follows: range x1 x2 x3 -10-0 2 5 1 (# points in this

Suppressing scientific notation on plot axis tick labels
Is there a better alternative to x = c(1e7, 2e7) x.lb = c(0,1e7,2e7) s.lb = format(x.lb, scientific = FALSE, big.mark = ",") barplot(x, yaxt = "n", ylab = "") axis(side = 2, at = x.lb, labels = s.lb) (I am sure there is a better alternative to line 2 :)). Thank you. -- View this message in context:

Verify the linear regression model used in R ( fundamental theory)
Hi, folks, As I understand, Least-squares Estimate (second-moment assumption) and the Method of Maximum Likelihood (full distribtuion assumption) are used for linear regression. I do >?lm, but the help file does not tell me the model employed in R. But in the book 'Introductory Statistics with R', it indicates R estimate the parameters using the method of Least-squares. However it

Variance of the prediction in the linear regression model (Theory and programming)
Hi, folks, Here are the codes: ############## y=1:10 x=c(1:9,1) lin=lm(log(y)~x) ### log(y) is following Normal distribution x=5:14 prediction=predict(lin,newdata=x) ##prediction=predict(lin) ############### 1. The codes do not work, and give the error message: Error in eval(predvars, data, env) : numeric 'envir' arg not of length one. But if I use the code after the pound sign, it

how to save summary(lm) and anova (lm) in format?
Hi, folks, I would like to copy the output of summary(lm) and anova (lm) in R to my word file. But the output will be a mess if I just copy after I call summary and anova. ##################### x=rnorm(10) y=rnorm(10,mean=3) lm=lm(y~x) summary(lm) Call: lm(formula = y ~ x) Residuals: Min 1Q Median 3Q Max -1.278567 -0.312017 0.001938 0.297578 1.310113

How to predict the mean and variance of the dependent variable after regression
Hi, folks, As seen in the following codes: x1=rlnorm(10) x2=rlnorm(10,mean=2) y=rlnorm(10,mean=10)### Fake dataset linmod=lm(log(y)~log(x1)+log(x2)) After the regression, I would like to know the mean of y. Since log(y) is normal and y is lognormal, I need to know the mean and variance of log(y) first. I tried mean (y) and mean(linmod), but either one is what I want. Any tips? Thanks in

How to 'understand' R functions besides reading R codes
Apologize for not being clearer earlier. I would like to ask again. Thank Joris and Markleeds for response. Two examples: 1. Function 'var'. In R, it is the sum of square divided by (n-1) but not by n. (I know this in R class) 2. Function 'lm'. In R, it is the residual sum of square divied by (n-2) not by n, the same as in the least squares estimate. But the assumption following

how to set the number format to pure numeric?
Hello, I want to export a numeric matrix in pure numeric format, i.e. I want 0.0001 to appear as "0.0001". But it seems the default setting for write.table is scientific notation, i.e. it will appear as "1e-04". how to set the number format to pure numeric? Thank you very much for your help. cheers, lichi shi

R numeric string problem
Hi, I have a text (.dat) file, in which each row contains several long numeric strings. One of the strings is 38 digits long, for example: 03200801200801172008011720092904008901 When I read in the data file, this string shows up as 3.200801e+36. To get rid of the scientific notation, I used "options(scipen=999)." When I did this, the scientific notation went away, but the numeric

y-axis number format on plot, barplot etc.
I am trying to change the number format shown on the y-axis from scientific 5e05, to 500,000 etc. Does anyone know how to do this? Is there something I can add as an argument to barplot, or would it be through par? barplot(data$Value, names.arg = as.vector(data$Field), main=strTitle) [[alternative HTML version deleted]]

barplot and NA
Am I wrong that barplot is supposed to just skip NAs, and continue with the rest of the data in a matrix column? That's how I read various posts on the subject. But that's not what happens for me with R64.app (on a Mac, obviously). For example: d0 <- as.matrix(c(2,3,4)) d1 <- as.matrix(c(2,3,NA)) d2 <- as.matrix(c(2,NA,4)) d3 <- as.matrix(c(NA,3,4)) barplot(d0) barplot(d1)

gap.barplot doesn't support data arrays?
I am trying to make a barplot with a broken axis using gap.barplot (in the indispensable plotrix package). This works well when the data is a vector: > twogrp<-c(rnorm(10)+4,rnorm(10)+20) > gap.barplot(twogrp,gap=c(8,16),xlab="Index",ytics=c(3,6,17,20),ylab="Group values",main="Barplot with gap") But when the data is an array (for a bar plot with multiple
