Dear: I am trying to plot the histogram graph for my observed data. Then plot fitted distribution on the same graph of histogram plot in R. 1. histogram plot y. 2. based on "1", plotting y1 v. x; 3. based on "1", plotting y2 v. x; 4. based on "1", plotting y3 v. x; All of these four plots must be on the same graph. However, I found the difficulty is

Dear: I want to plot barplot and let bar be in the middle of each x axis category. Do you have this experience? Many Thanks! Xin [[alternative HTML version deleted]]

Dear All: I am trying to read the data from the different sheet but in the same Excel file. Does R provide this kind of command to do it? Anyone has experience on this? Thanks! Xin [[alternative HTML version deleted]]

The summary stats for the xin and yin variables below are correct. However, if I use plot(xin,yin), an exception is thrown saying that "object xin is not found." Also, it is apparent that I can't successfully replace the x and y vectors with values from xin and yin. The four plots on one panel are showing but the range of x and y is only [0,1], and therefore, it seems like an

Hi to all, how could I to rotate automatically a data sheet which was imported by read.xls? x1 x2 x3 .... xn y1 1 4 7 ... xn/y1 y2 2 5 8 .... xn/y2 y3 3 6 9 ....xn/y2 yn ... ... ... Xn/Yn to y1 y2 y3 .... yn x1 1 2 3 ..... Yn/x1 x2 4 5 6 .... Yn/x2 x3 7 8 9 .... Yn/x2 xn ... ... ... ..... Yn/xn Kind regards Knut

Dear I try to add three different lines (solid, short dash, long dash) in to current barplot. I saw there are types of lines ("p","b", ect). However, they are not what I request. Has nayone have this experience? Many Thanks! Xin [[alternative HTML version deleted]]

Dear All: I tried to fit negative binomial distribution to data in terms of mean and mean is also a quadratic function of another variable. The likelihood function is: function (parameters, y1,x11) { p<-parameters[1] alpha1<-parameters[1] beta1<-parameters[2] delta1<-parameters[3] mu<-alpha1+beta1*(x11)+delta1*(x11^2) ifelse(y1>=0|x11>=0, L<-

Dear All: I used optim() to minimise the loglikelihood function for fitting data to negative binomial distribution. But there initial value of log-likelihood and iteration 10 value are reasonable. for example: initial value 1451657.994524 iter 10 value 47297.534905 iter 20 value -623478636.8236478 Then the iter 20 vlaue suddelnly changes to a negative value and in the end the error mesage is

Dear: I have two series data, which are: p1-obs p1-exp 13 13 20 23.296 22 18.139 19 14.972 10 12.576 16 10.658 8 9.0794 4 7.7625 3 6.6536 5 5.7141 7 4.9146 4 4.2321 0 3.648 4 3.1471 4 2.7168 2 2.3468 4 2.0283 2 1.7537 2 1.517 5 1.3127 1 1.1362

Dear All: I am trying to plot a series of data using histogram plot. But I want to change the default of setting for histogram plot. For example, I want to set frequency plot starting with zero. Many Thanks Xin [[alternative HTML version deleted]]

Dear: I am trying to merge two tables by a common variable. However, there are a few same variables which are in both of two tables. How can I take them away when I merge the two tables? Thanks! Xin

I used the command below, but R gives me the error message--syntax error. can anyone see the mistakes I made? optimize(function(x,y) + ((327.727-(1-0.114^10)*y*(1-x)/x/(1-x^y))+(9517.336-327.727 *(1+(1-x)*(1+y)/x-327.727)))^2 + interval=c(0,1)) At the same time, I use nlm() but R gives me the code $code [1] 3 function(vals) { x <- vals[1] y <- vals[2]

Hi all, Is there any way to keep numeric colnames as is? Any hint will be appreicated. Xin Zheng [[alternative HTML version deleted]]

I'm new in both R and statistics. I "did my homework", I tried the archives and whatever I managed to get from the sources, but still I need assistance with the plsr package. I have a model with 2 core determinants D1 and D2, made by 3 indicators each (D1a,D1b,D1c and so on). Also I have 2 moderating variables (m1,m2), where m1 moderates D1 and m2 modarates D2. The dependent

Dear R-helpers, I am sorry for asking something I know has been asked before, I have tried different combinations in the strip function without success... I am using version 2.5.1 and work on a PC. I have barcharts generated from the following formula: barchart(y1+y2+y3~x | g) I need to change the names of the variables y1,y2 or y3 that currently appear in the strips, I have two

Dear all: I fitted "Observed" into a distribution as frequency. The predicted values are calculated as "predicted" for frequency. bins is "x". I plot observed, predicted against x in a graph. the commond is here.

Dear All, I need some help arranging data that was imported. The imported data frame looks something like this (the actual file is huge, so this is example data) DF: IDKey X1 Y1 X2 Y2 X3 Y3 X4 Y4 Name1 21 15 25 10 Name2 15 18 35 24 27 45 Name3 17 21 30 22 15 40 32 55 I would like to create a new data frame with the following NewDF: IDKey X Y Name1 21 15 Name1

Hi guys... I have problem with this excersise... Consider the pressure data frame again. (a) Plot pressure against temperature, and use the following command to pass a curve through these data: > curve((0.168 + 0.007*x)?(20/3), from=0, to=400, add=TRUE) (b) Now, apply the power transformation y3/20 to the pressure data values. Plot these transformed values against temperature. Is a linear
