Align Multiple Tables Side By Side


Answer :

Just put two data frames in a list, e.g.

t1 <- head(mtcars)[1:3] t2 <- head(mtcars)[4:6] knitr::kable(list(t1, t2))

Note this requires knitr >= 1.13.


I used this Align two data.frames next to each other with knitr? which shows how to do it in html and this https://tex.stackexchange.com/questions/2832/how-can-i-have-two-tables-side-by-side to align 2 Latex tables next to each other. It seems that you cannot freely adjust the lines of the table as you can do it with xtable (does anybody know more about this?). With format = Latex you get a horizontal line after each row. But the documentation shows two examples for other formats. One using the longtable package (additional argument: longtable = TRUE) and the other using the booktabs package (booktabs = TRUE). 

--- title: "sample" output: pdf_document header-includes: - \usepackage{booktabs} ---  ```{r global_options, R.options=knitr::opts_chunk$set(warning=FALSE, message=FALSE)} ```   ```{r sample, echo=FALSE, results='asis'} library(knitr) library(xtable)  t1 <- kable(head(mtcars)[1:3], format = "latex", booktabs = TRUE) t2 <- kable(head(mtcars)[4:6], format = "latex", booktabs = TRUE)  cat(c("\\begin{table}[!htb]     \\begin{minipage}{.5\\linewidth}       \\caption{}       \\centering",         t1,     "\\end{minipage}%     \\begin{minipage}{.5\\linewidth}       \\centering         \\caption{}",         t2,     "\\end{minipage}  \\end{table}" ))   ```

here a solution for html documents

(As this question was asked very broadly and not specifically referring to LaTeX).

Requires knitr and kableExtra

--- title: "Side by side" output: html_document ---   ```{r sample, echo=FALSE} library(knitr) library(kableExtra) t1 <- head(mtcars)[1:3] t2 <- head(mtcars)[4:6] ``` ## as list ```{r} kable(list(t1, t2)) ```  ## with float ```{r, echo = FALSE} kable(t1) %>%   kable_styling(full_width = FALSE, position = "float_left") kable(t2) %>%   kable_styling(full_width = FALSE, position = "left") ```

It is intentional that table t2 gets position = "left". If you allow it to float, this will not block the rest of the paragraph and mess up the following lines in your document.

result:

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
