hello, i already include the error in blue color word. i hope it can help you to understand my question. if not burden you, please give me a guide how to correct the error or maybe you can correct the coding cause error. thank you. > # lda.r > # > # Author: Amsha Nahid, Jairus Bowne, Gerard Murray > # Purpose: Perform Linear Discriminant Analysis (LDA) > # > #

HELLO, anybody... could you help me to check the below coding for volcano. what is the mistake? what the plot could not display? # volcano_plot.r # # Author: Amsha Nahid, Jairus Bowne, Gerard Murray # Purpose: Produces a volcano plot # # Input: Data matrix as specified in Data-matrix-format.pdf # Output: Plots log2(fold change) vs log10(t-test P-value) # #

Hello. My name is Akashah. i work at metabolic laboratory. From my study, i found that volcano plot can help a lot in my section.  i already studied about the volcano plot and get the coding to run in R software, unfortunately, there is may be something wrong with the coding. This is because  no graph appear, but no error (blue color text) was shown on the R console. Below is the coding for

Hi, what i need is as the example i attached in the box plot. As you can see, the boxplot have margins and it kind of follow the coding I've added, but, it does not happen for the heat map. Could you help me with this.. Thanks in advance. the following is the coding i've used: # Draw the heatmap # heatmap.r # # Purpose: Create a heatmap # # Input: Data matrix as

Greetings list, I am new to programming in R, and am using nnet() function for a project on neural networking. Firstly I wish to ask if there is any pdf explaining the algorithm nnet uses, which could tell me what the objects of the nnet class, like 'conn', 'nconn, 'nsunits', n and 'nunits' mean, and how weights are calculated. The package pdf has little or no

This is a simple problem, but a mystery to me. I'm trying to grab $Family "Scelionidae" from one dataframe and put it into another dataframe occupied with NA in $Family. The result is a "158" ends up there instead of Scelionidae. Simply put fam$Family[1] <- least$Family[1] If I have made a mistake here, can somebody point it out. I've included the simple

Your data frame fam contains factors. Turn it into character strings using fam$Family = as.character(fam$Family) and try again. It may be helpful if you read up on R's factors, see ?factor.

Hi there, I am a master student in Denmark, and apply R to analyze the drug data. I use the function 'lda' to obtain a linear discriminant object, and then wish to use 'plot.lda' to do the plot on this object like below. drug.lda <- lda(Inhibition ~ NET_CHARGE + PKA_1 + MW + MLOGP, data = drug.class, method = "moment") plot.lda(drug.lda,

Hi, I have done different discriminant function analysis of multivariat data. With the CV=True option I was not able to perform the predict() call. What do I have to do? Or is there no possibility at all? You also need the predicted values to produce a plot of the analysis, as far as I know. Here my code: pcor.lda2<-lda(pcor~habarea+hcom+isol+flowcov+herbh+inclin+windprot+shrubcov+baregr,

Full_Name: Cornell Gonschior Version: 2.10.0 OS: Linux Submission from: (NULL) (212.201.28.40) Hi, in the introduction to R, you can find the following sentence in the par() chapter: "Use tck=0.01 and mgp=c(1,-1.5,0) for internal tick marks." I thought that's nice, because I wanted to have tick marks and tick labels inside and the axis title outside. But: > plot(z, las=1,

Well, ?factor does not say anything about this behaviour (assigning numeric code instead of level of factor). And actually if you do assignment for whole vector the result is different (vector in data frame is changed to factor). > temp2$fff[1]<-vec[1] > head(temp2,2) pokus minuty fff 1 T42 240 3 2 T42 300 <NA> > temp2$fff<-vec > head(temp2,2) pokus

It seems that when an argument 'mgp' is supplied to axis(), the mgp[2] value (position of tick mark labels) is honoured but the mgp[3] value (position of axis line) is ignored. Example: plot(1:5, xaxt='n', ann=FALSE) par(mgp=c(0,2,1)) axis(1, at=2:4, mgp=c(0,-2,-3)) Axis line is plotted at margin line 1, tick mark labels at line -3. Is this a bug? J. R. M. Hosking

Hi, I'am trying to make a multiple bar plot over a map and I'm having difficulties with the distance between axes labels and the axis. Trying to control this with mgp does not help because it controls both axes simultaneously. For example, with default values (mgp = c(3, 1, 0)) y-axis labels are ok, but x-axis labels are not. Setting mgp = c(3, 0, 0) gives good x-axis labels but the

Hello, I am trying to use mgp.axis labels to locate the x-xis at a different distance from the one specified for the y-axis. I know I could use other functions such as mtext or axis. But I am curious to know about how to use 'mgp'axis.labels' from the Hmisc package. I tried following the example in the documentation without success. Sample code: x<-1:10 y<-1:10

Hi, I have created a plot using filled.contour() and have the problem that one of the axis titles and an axis label are overlapping. I have tried changing par()$mgp (with, e.g. par(mgp=c(4,1,0)) ), but this just makes the title go off the screen. I can't work out how to make the plot take up less space in the window, so I can hopefully change mgp and sort the problem. Is changing mgp the only

Hello, I am trying to port one of my plotting S+ functions to R and I am having difficulties!!! I am including here only the troublesome code! I first produce a barplot, saving the positions of the bar's centers. par(mar = c(6.1, 5.1, 4.1, 4.1), mgp = c(3, 3.0, 0)) ticks.loc <- barplot(sum.of.weights, col = 5, xlab = "", ylab = "", axes =

I have long axis labels (8units) on the x axis and 2 unit number labels on the y axis. I need to move the x axis title without moving the y axis title. I have used mgp=c(title, label and line), but mgp moves both the x and y titles. The following puts the y axis title way way out to the left. Anyone know how to move just the x axis.
