similar to: Problem with ifelse statement

Hi R-helpers, Please see the below R output. The problem is that after running the ifelse statement, data$SOCIAL_STATUS is converted from a factor to a character. Is there some way I can avoid this conversion? Thanks in advance, Mark Na > str(data) 'data.frame': 2100 obs. of 11 variables: $ DATE : Factor w/ 5 levels "4-Jun-09","7-May-09",..: 1 1 1 1 1

I'm sorry if this is a basic question, but I'm stumped. I'm just trying to plot the residuals from a linear model against another variable in the data frame. Here are the lines I'm trying to execute: size <- read.table(file="/u67/abasl70/surveys/annenberg/mega/smschl.dat", header=T) sizef <- data.frame(size, row.names=size$unit) attach(sizef) mschmod <- lm

Hi R-helpers, I would like to subset my dataframe, keeping only those rows which satisfy the following conditions: 1) the string "dnv" is found in at least one column; 2) the value in the column previous to the one "dnv" is found in is not "0" Here's what my data look like: ??? POND_ID 2009-05-07 2009-05-15 2009-05-21 2009-05-28 2009-06-04 4 ? ? ? 101 ? ? ?

Dear R-helpers, I have split a dataframe into a list with five elements, with the following code: > datalist<-split(data,data$UNIT) I would now like to run some code (below) on each element of the list to extract rows from the list elements; then I would like to rbind the extracted rows into a new dataframe containing all of the extracted rows from all of the list elements. I don't

Hi everyone, I?m a student and relatively new to R so apologies in advance if this question seems stupid or obvious to you. I have collected a dataset with about 60 species of diatoms (count data from 19 different sample sites) and environmental variables for each site (salinity, pH, etc.). It?s all in the same dataset but distinct in R through the functions below diat <- diatom [, 1:60]

Hi, My data.frame "A" has FID like this FID a a b b b c c d d d d Now my second data.frame "B" has age value for a, b, c, d like FID Age a      5 b      7 c      9 d      3 How can search for the Age column in "B" and replace the values in "A" so that my new "A" looks like this FID Age a      5 a      5 b      7 b      7 b      7

Hi all, I am interested in performing a cluster analysis on ecological data from forests in Pennsylvania. I would like to develop definitions for forest types (red maple forests, upland oak forests, etc.(AH AR in attached table)) based on measured attributes in each forest type. To do this, I would like to 'draw clusters' around forest types based on information from various tree

Dear List, I have hit this problem with using a plotmath expression in an axis label on a lattice plot I'm including in a Sweave document. The actual document is far too long and boring (unless you are interested in the hydrochemistry of upland lakes) to include here, but the following minimal example reproduces the problem; basically, the PDF produced by Sweave has missing characters in the

Hi, I'm investigating the size of Clang's generated binaries relative to GCC, when targeting Android, and I've noticed that Clang's exception tables are much larger -- the .ARM.extab section is about 2.5 times as large in two examples. I noticed a couple of differences between Clang and GCC: 1. *ULEB128 encoding.* In the call site table, GCC encodes offsets using a ULEB128
