Dear Ruser's I ask for helps on how to substitute missing values (NAs) by mean of the group it is belonging to. my dummy dataframe is: > df group traits 1 BSPy01-10 NA 2 BSPy01-10 7.3 3 BSPy01-10 7.3 4 BSPy01-11 5.3 5 BSPy01-11 5.4 6 BSPy01-11 5.6 7 BSPy01-11 NA 8 BSPy01-11 NA 9 BSPy01-11 4.8 10 BSPy01-12 8.1 11 BSPy01-12 6.0 12

Dear R-helpers, Very small amount of outliers can greatly affect the mean and many other statistic of a numeric variable. So, usually we must deal with the outliers properly in the process of data analysis. Here, I want to replace outliers with the group median of the variable. But, I can not construct a good way to do that efficiently, because of I am a newbie to R and programming. Can anybody

Hello all R users, I have a problems transforming (or maybe better regrouping) a data.frame. I have a big data.frame, which I would like to sum up according to a specific column. This is an example of my matrix: ID gen 0042787 gen2 0016070 gen2 0016070 gen3 0007409 Gen1 0007409 gen3 0006511 gen2 0006417 gen3 0016070 gen4 0006511 gen4 I want to rearrange the matrix

Good Evening R-Help Community: I have attached a file that contains the output from sessionInfo() and a summary of my Win XP system. I am?running R 2.12.0 and using Tinn-R 2.3.6.2 as my interface. When I attempt to call either the doBy or coin packages R generates an error that I do not understand and have so far not been able to resolve by searching R resources. I exchanged a couple of

I tried Tal's suggestion of deleting the doBy and coin packages and then reinstalling them from a different mirror. The first install was from the Harvard mirror and the second was from the Case Western Univ. mirror. The new packages generate the same errors when I call them using the library() command. Also, I tried to load these packages using R and its script editor thinking that the

Greetings R Community, One of my favorite packages won't load and I'm not sure why. It loaded earlier today. The problem appears with the snow package, which doBy requires. I tried reinstalling both packages again ,shutting [R] down, reinstalling [R] in the workspace (shortcut). Here's the weird thing. The same exact library loads in another workspace using the same version of [R]

You can install any R packages from CRAN using the ?"install.packages()" command form within R itself. This will download, compile, and install the packages into your personal user account. you might need to install some supporting *-devel RPM packages via "yum", but otherwise, it should work. --------------------------------------------------------------------------- Jason

Hello R users, I'm analyzing an experiment in a balanced incomplet block design (BIB). The effect of blocks are assumed to be random, so I'm using nlme::lme for this. I'm analysing another more complex experiments and I notice some diferences from doBy::popMeans() compared multcomp::glht() and contrast::contrast(). In my example, glht() and contrast() were equal I suspect popMeans()

Dear R-listers, I have created a plot to display the density lines for the same variable by different entities. Now, I want to fill the area under the density lines with semitransparent colors. Though I have checked that in web-searching and book-reading, I still do not perform that. Could anyone please give me any helps or advice? Thank you in advance. The data and code I used listed below: #

I have a question regarding?the very useful doBy package, and specifically, the transformBy() function?with the lag() and diff() functions. ?It is often useful to lag or difference data within a panel, i.e., within a by-group. ?Is the following code a safe use of transformBy? Is there an alternative? First, does the initial "orderBy" statement guarantee that the Time order will be

I have a R script that I am running from python with rpy2. On a debian system I run this: apt-get install R-cran-ggplot2 R-cran-caret And the script works. I want to move this to CentOS 7 system. There it cannot find R-cran-ggplot2 or R-cran-caret. Does anyone know what packages in CentOS 7 I need for dplyr, doBy, and ggplot2?

Dear R-listers, There is my data and my codes to create a plot. I want to know why there are two small circles in the upper right and lower left of the plot respectively.

Dear R-listers, I do clustering on tens of individuals by thousands of traits. I have known the assignment of each individual. I want to classify the individuals by randomly resampling different subsets of the traits, for example, randomly resampling 100 traits for 100 times, then 200 traits for 100 times, then 300 traits for 100 times, ,,,,,,. By each subset of traits, I do clustering of the
