I'm Knit To PDF the R-notebook containing the following code:
import matplotlib
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.pyplot as plt
import numpy as np
t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2*np.pi*t)
plt.plot(t, s)
plt.xlabel('time (s)')
plt.ylabel('voltage (mV)')
plt.title('About as simple as it gets, folks')
plt.grid(True)
plt.savefig("test.png")
plt.show()
When I choose Knit To PDF, this error appears:
This application failed to start because it could not find or load the Qt platform plugin "windows" in "". Reinstalling the application may fix this problem.
On the other hand, when choosing to Knit To PDF a R-notebook that contains only R code, everything works fine.
Could you please help me resolve this error?
