We are trying to use Gstreamer's mpegts pluging to record a video stream stream using the following Gstreamer example code https://gstreamer.freedesktop.org/documentation/mpegtsmux/mpegtsmux.html?gi-language=c. When we compile the code using gcc mpegtstest.c -o mpegtstest `pkg-config --cflags --libs gstreamer-1.0 gstreamer-mpegts-1.0` -v everything works as expected and the program records with no issues. We are now trying to compile the code using cmake and make. cmake generates correctly but make fails with error. /usr/bin/ld: cannot find -lgstreamer-mpegts-1.0.

Here is some example data:

I am not sure exactly how to override aesthetic properties of a custom plot made with ggplot. The only way I could think of right now was using the functionality of the grid package, though is really hackish. Maybe there is a easier way, like using guides or so from ggplot2, though I could't manage to make it work?

Below is an example where I just want to adjust the line width in the graph. Of course, I would like that to trickle down in the legend as well. So, below are my steps with grid, but any simpler solution is greatly appreciated (ideally something that doesn't need grid but just ggplot2, if possible).

What is the correct way to use the generic type in this situation? Consider the following code:

I have created an gtable (also gTree grob gDesc) object myobj via myobj <- gridExtra::grid.arrange(g1,g2) from two ggplot objects g1,g2 some time ago and now I have to restore the data that I have used to create both ggplots. Is there a way to do this properly?

I have already tried to convert myobj using various functions, e.g., ggpubr::as_ggplot, resulting in an object with a waiver() as $data entry - so no success there - and I have also swept all the grobs entries in myobj where I in fact found the data points in the plot (looking like this

I'm looking for a way to add minor tick marks to ggplots without using coord_cartesian(clip = "off"). Or a way to reproducible apply clipping to the x axis but not the y axis, or vice versa.

So far I have been using the annotation_ticks() function and the GeomTicks geom defined in this excellent answer here (with some minor modifications to make it work with ggplot2 v3.3.0). Unfortunately, for the tick mark annotations to appear on the outside of the plot one must use coord_cartesian(clip = "off") which means anything else that sits outside the plotting area is also exposed (see reprex below).

Alternatively, perhaps there is a way to leverage any of the new capabilities of ggplot2 v3.3.0 to draw minor ticks not as an annotation but as an actual part of the axis/plot so that it is possible to draw them outside the plotting area.

I am not a software developer but perhaps one could define a new theme element using register_theme_elements called axis.minor.ticks that behaves like axis.ticks but gets the appropriate location of the minor ticks from panel_params$y$break_positions_minor instead of panel_params$y$break_positions. Or somehow use the new guide_x() S3 functions.

Any help would be much appreciated!

The annotation_ticks() function (incorporating this fix for faceting issue):

I am trying to save dataframe into hdfs system. It gets saved as part-0000 and into multiple parts. I want to save it as an excel sheet or just one part file? How can we achieve this?

code used so far:

I'm not sure if I'm missing something and that might make this question very stupid. But I can't understand why the hell it's failing after trying pretty much every approach one could have.

So, super simple, I have this GLib Tree and I want to insert stuff into it in other functions. Why none of the options presented below work? I can understand the first failing more than the second to be completely honest.

I need something like the following, but with a different color for each word in the String:
