I want to write an equation in Jupyter notebook's markdown cell which contains text with space. I tried writing the following.
\begin{equation*}
e^{i\pi} + 1 + some text = 0
\end{equation*}
Which results like this.
How to add space between "some" and "text"? Thank you.
You can try wrapping your text in \text{}.
\begin{equation}
e^{i\pi} + 1 + \text{some text} = 0
\end{equation}
Note: this is more of a latex question, to which you can get answers from here.
In addition, you could consider " \ " and "\quad" directives to add horizontal space between elements in a LaTeX environment, also "\hskip".

I am creating a html report using R Markdown. The first paragraph contains a list of categories represented by certain samples with short descriptions. Here is an example:
This is the test list:
* **first group**:
+ **item 1** - this is the description of an item
* **second group**:
+ **item 2** - this is the description of an item
+ **item 3** - this is the description of an item
* **third group**:
+ **item 4** - this is the description of an item
* **fourth group**:
+ **item 5** - this is the description of an item
+ **item 6** - this is the description of an item
The text was inserted outside the code chunks. I would like to preserve this (even) spacing between the lines in knitted document, so it would be easy readable. Otherwise it looks too squished. Unfortunately R Markdown changes spacing, so some of them are uneven. I tried using trailing spaces and defining line breaks with br, but nothing changed. I could off course edit the html file manually after knitting, but this is a brute force way. R Markdown has to have some option to deal with it - but I was not able to figure it out myself. Would appreciate any help.
You could add a css tag at the start of your rmarkdown document to specify how you would like the html output to interpret line heights:
```{css}
li {
line-height: 3;
}

I have written a plain text in notepad editor. This text contains some embedded mathematical formulas like \sumw_if(x_i) which refers to \sumw_if(x_i) or \alpha^2 + \beta^2 = \gamma^2 which refers to \alpha^2 + \beta^2 = \gamma^2etc.
Now, I'm looking for a way to autocorrect all those formulas within ms-word. First I tought to select formulas one by one and then "ALT +" to get the maths notation. This method works fine but it's frustrating because I have a bunch of equations
Is there any help? Macros, MathML or other tips?
Regards
If the embedded mathematical formulas were delimited with dollar signs -- e.g., $\alpha^2 + \beta^2 = \gamma^2$ -- MathType can do it with its Toggle TeX feature. If it's something you want to do programmatically, there's the MathType SDK.
I have managed to write the whole equation
using the following code in Rmarkdown
$$MAPE = \frac{1}{n} \sum_{d_i} (\frac{1}{q} \sum_{t_j}
\abs{\frac{gap_{i,j}-s_{i,j}}{gap_{i,j}}} )$$
However, in Rmarkdown, the code above returns:
Could anyone help figure out how to get abs right here?
Thanks
Expanding on Andrie's answer:
Another way to write absolute value is
\lvert -3 \rvert
To automatically adjust the size of the vertical lines to what's inside them, use
\left\lvert -3 \right\rvert
In your case, this becomes:
$$MAPE = \frac{1}{n} \sum_{d_i} (\frac{1}{q} \sum_{t_j}\left\lvert{\frac{gap_{i,j}-s_{i,j}}{gap_{i,j}}}\right\rvert)$$
edit: When I originally posted this answer, I couldn't embed images yet. Now replaced link with embed.
Using mathjax, you can use the "pipe" symbol |to indicate absolute values.
Try this:
$$ |-3| $$
In your case:
$$MAPE = \frac{1}{n} \sum_{d_i} (\frac{1}{q} \sum_{t_j} |\frac{gap_{i,j}-s_{i,j}}{gap_{i,j}}| )$$
This gives:
I would like to add a text to my plot so that one letter, a, appears bold. I started with the following, but the result is not what I need:
plot(1:5,axes=F)
mtext(c(only a should be bold),1:1,font=2)
What should I do to make only a bold?
Complex text editing can be done with expression. See ?plotmath for a list of commands.
mtext(expression(paste("only ", bold("a"), " should be bold")), 1, 1)
I wish to print a text in the title in two lines but am not able to achieve desired output because of subscript present in the text. Following is the e.g of the text that I want in two lines.
plot(1,main=expression(paste(CO[2]~'Flux (kg C ', m^-2,' ',s^-1,')')))
BUT using line break as in following command does not give desired result of bringing (only) the text following it in new line:
plot(1,main=expression(paste(CO[2]~'Flux \n(kg C ', m^-2,' ',s^-1,')')))
Please help me with this issue.
Thanks in advance
You can do this with the atop function.
plot(1,main=expression(atop(CO[2]~'Flux', paste('(kg C ', m^-2,' ',s^-1,')'))))
Since the lheight par doesn't affect expressions, if you want tighter spacing between the lines, you can use the following.
plot(1,main=expression(textstyle(atop(CO[2]~'Flux', paste('(kg C ', m^-2,' ',s^-1,')')))),
cex.main=2)
