For my individual assignment, I'm trying to filter a column that has some NA values to show values that are above a threshold. R comes back with:

sgriff_loadyields %>%

• select(state:nitrogen) %>%
• filter(nitrogen >= 1000) %>%
• summarize(n = n())
  n
  1 0
  Warning message:
  In Ops.factor(c(29L, NA, NA, 34L, NA, 39L, 1L, 4L, 19L, 22L, NA, :
  ‘>=’ not meaningful for factors

I've tried many different combos of using na.omit, na.strings"", or na.rm=TRUE, or as.numeric. I don't know how else to filter using this dataset.

error: unable to read askpass response from 'rpostback-askpass'
fatal: could not read Username for 'https://github.com': Device not configured

I can click the initial "Submit New Pull Request" button from the env-info page, but the next step, the green button is faded and I cannot click on it. I don't see an open Pull Request in my name. Not sure what the cause of this is!

Thanks!

I've been getting a weird error message whenever I try to knit the individual assignment to HTML. I've been adding eval = F to the beginnings of the Rchunks when needed. When I try knitting my Rmd, I get this message in the console:

The index.html is not showing up at http://pollute.github.io, and we're getting an email that says:

[pollute/pollute.github.io] Page build failure

From: GitHub [email protected]

The page build failed with the following error:

The submodule pollute was not properly initialized with a .gitmodules file. For more information, see https://help.github.com/articles/page-build-failed-missing-submodule.

It looks like the R chunk to install the packages isn't working. (On the Week 3: Tutorial on Reading and Wrangling Data page: http://ucsb-bren.github.io/env-info/wk03_dplyr/wk03_dplyr.html#install-packages)

I think the final install.packages command just needs quotes around the p, as follows.

# install packages if not found
for (p in pkgs){
  if (!require(p, character.only=T)){
    install.packages("p")
  }
}

My tidyr code seems to work fine, but the kniting process fails when I try to use "gather" code. The error reads:

"Error in eval(expr, envir, enclos): not compatible with STRSXP calls: ... -> select_Vars_ -> combine_vars ->.Call"

any hints? I submitted a pull request so you can look at my code (kboysen.rmd)

Receiving the error message when trying to add chunk with a read.csv command. Not sure how else to fix this other than setwd(), but wouldn't that create a problem for anyone opening the file on another computer?
