kableextra

问题 I would like to create a pdf with rmarkdown. The PDF should contain a table. The table should have a dynamic column label. The tabhead should display the calendar week. However, the calendar week (e.g., KW29) is not displayed but the variable name "kw0". What is my error? library(knitr) library(kableExtra) library(lubridate) options(knitr.table.format = "latex") loadData <- function() {# load some data} myData<- loadData () kw0 <- paste("KW", week(Sys.Date()) - 1, sep = "") kw1 <- paste("KW",

问题 I use the kableExtra package to generate a long table in an R markdown documents knitted to PDF. Sets of rows of the table are grouped together using kableExtra::pack_rows() (formerly kableExtra::group_rows() ) Two issues arise: If the last row forms a set, its grouping is not displayed if one sets longtable = TRUE to allow the long table to span across multiple pages and at the same time uses kable_styling(..., latex_options = c("repeat_header")) to repeat the header of the table on each

I would like to align all columns in a kableExtra table to the top. The valign = "top" option does not seem to solve the issue here. Also, the third column is somehow dropped on top of the second for some reason, and citations are not working too. The MWE below is based on this related SO question, which only needs 2 columns: kable:

问题 Is there a way to increase the line spacing with kableExtra for a pdf output in r-markdown or bookdown? library(knitr) library(kableExtra) kable( head(iris, 5), caption = 'Iris Table', booktabs = TRUE) %>% kable_styling(latex_options = "striped") 回答1: You can just do it using the LaTeX command \arraystretch : --- output: pdf_document --- ```{r setup, include=FALSE} library(kableExtra) library(tidyverse) ``` \renewcommand{\arraystretch}{2} ```{r, echo=FALSE} library(knitr) library(kableExtra)

问题 My data frame has ugly column names, but when displaying the table in my report, I want to their "real" names including special characters '(', new lines, greek letters, repeated names, etc. Is there an easy way of replacing the names in knitr to allow such formatting? Proposed solution What I have tried to do is suppress the printing of the data frame names and use add_header_above for better names and names that span several columns. Some advice I've seen says to use: x <- kable(df) gsub("

问题 I am trying to create a table using kable/kableextra without showing the horizontal lines in the table except for the first row which is the row names. ``` {r echo=FALSE} library(knitr) library(kableExtra) options(knitr.kable.NA = '') dt <- mtcars[1:5, 1:6] kable(dt, "html") %>% kable_styling(full_width = F, position = "left") %>% row_spec(0, align = "c",bold=T ) %>% column_spec(1, bold = T) ``` In the code above there is a line below the first row, which I like since those are row names, but

问题 I should probably point out that I am still fairly new to working with RMarkdown and the kableExtra R package, but I have a document that was knitable last week and now no longer knits despite no physical changes to the document. The error message I receive is the following Error in save_kable_latex(x, file, latex_header_includes, keep_tex) : We hit an error when trying to use magick to read the generated PDF file. You may check your magick installation and try to use the magick::image_read
